DETAILED DESCRIPTION OF THE INVENTION The present invention will be illustrated in detail hereinafter with reference to the accompanying drawings and to the specific embodiment to make the purpose, technical solutions and the merits of the present invention more clear.

In view of the problems in the background art and the differences between frequency division duplex (FDD) systems and time division duplex (TDD) systems, the embodiments of the present invention provide a new solution for the configuration of uplink SR, which includes: determining a transmission transmission period of the SR and an uplink substructure for transmission of the SR according to the UE service information in a cell; determine resources of the SR available in each uplink substructure for the transmission of the SR according to the total amount of resources of the SR in the cell and the number of uplink substructures for SR transmission, assign the determined resources for the transmission of the SR (hereinafter SR resources for short) and at least one uplink substructure corresponding to the resources of the SR to the UEs; and notifying each UE of the resources of the SR, the at least one uplink substructure corresponding to the resources of the SR and the transmission cycle period of the SR.

When the resources of the SR of a UE are configured, the information related to the SR is configured for the UE according to the transmission cycle period of the SR, the uplink substructure for the transmission of the SR and the resources of the SR. SR available in the uplink substructure. Then, the UE can load an uplink SR in the uplink substructure for the transmission of the SR during the transmission cycle period of the SR by using the resources of the SR assigned to the UE.

Figure 1 is a flow chart illustrating a general method for configuring the uplink SR according to an embodiment of the present invention. As shown in Figure 1, the method may include the following steps.

In step 101, a base station determines a SR transmission cycling period and an uplink substructure within the transmission cycle period of the SR for each UE according to the service information of the UEs in a cell.

When the transmission cycling period of the SR is determined, the same transmission cycling period of the SR can be configured for all the UEs in the cell or a transmission transmission period of the SR can be configured for each UE of according to a user level and a UE service level. Different ways can be adopted to determine the uplink substructure for SR transmission for FDD systems and TDD systems.

In step 102, the base station determines the resources of the SR available in each uplink substructure for the transmission of the SR according to the total amount of resources of the SR in the cell and the number of the link substructures ascending for the transmission of the SR in the transmission cycle period of the SR and assigns, the resources of the SR determined to the UEs.

In step 103, the base station sends the transmission cycle period of the SR determined for each UE, the resources of the SR allocated to the UE, the substructure of uplink corresponding to the resources of the SR to the UE.

By sending SR resources, the base station can identify resources using SR resource indices or other identification information that are preconfigured for SR resources. To send the uplink substructure corresponding to the resources of the SR, the uplink substructure can be identified by using a lag of the substructure of the uplink substructure in the cycle period of transmission of the SR by bicycle or using any other information that uniquely identifies the substructure. To send the transmission cycle period of the SR, the base station may adopt cell broadcast or notify each UE, respectively, when using the upper layer signaling.

The UE, according to the information sent by the base station in step 103, can transmit an uplink SR using the resources of the SR allocated in the specified uplink substructure in the transmission cycling period of the SR.

Thus, the process for configuring the uplink SR according to one embodiment of the present invention is completed. As can be seen from the process, in the embodiment of the present invention, the transmission cycle period of the UE SR, the uplink substructure for the transmission of the SR and the resources of the SR are determined in sequence and the information of the above elements are sent to the UE and the configuration of the SR is carried out.

The above is the method for configuring the uplink SR. In the previous process, when the resources of the SR allocated to a certain UE have not been used for a certain period, the base station can release the allocated resources of the SR, so that another UE can use the resources of the SR for the transmission of the SR.

A detailed implementation of the embodiments of the present invention will be described. It is assumed that the uplink substructure corresponding to the resources of the SR is identified by using the substructure lag of the uplink substructure in the transmission cycle period of the SR and the preconfigured resource indices of the SR they are used to identify specific resources of the SR.

Fig. 2 is a flow chart illustrating a detailed method for configuring the uplink SR according to an embodiment of the present invention. As shown in Figure 2, the method may include the following steps.

In step 201, a base station determines a transmission cycling period of the SR for each UE according to the service information of the UEs in a cell.

The transmission cycling period of the SR is determined taking into account the general charges and the time delay under consideration. When the transmission cycle period of the SR is long, the overall load is small but the programmed time delay is large; when the transmission cycle period of the SR is short, the overall load is large, but the programmed delay time is small.

In an optional solution, all the UEs in the cell have the same transmission cycling period of the SR and the transmission cycling period of the SR is sent to the UEs by system broadcasting.

In practice, different UEs may have different requirements for the time delay and may need different periods of transmission cycling from the SR, thus, different transmission cycling periods of the SR may be configured for different UEs, which may improve the flexibility of the configuration of the SR, make full use of the limited resources of the SR and reduce the delay of the service. But the UEs must be notified of the respective periods of transmission cycling of the SR, therefore, the overall load of the system is increased. Therefore, there is a trade off between the general load and the time delay according to the needs of the practical applications.

In one embodiment of the invention, a configuration form for configuring the transmission cycling period of the SR is first selected according to the number of UEs in each cell and the number of service types and then the transmission cycling periods are determined. of the SR of the EU.

There are two ways to configure the transmission cycle period of the SR, one includes configuring the same transmission cycle period of the SR for all the UEs in the cell, the other includes configuring different periods of transmission cycling of the SR for the UEs according to a user level and a service level of each UE in the cell.

Preferably, when the number of the UEs in the cell and the number of the service types of the UEs is small, for example, fen a rural area, the first way and the same period of transmission cycling of the SR can be adopted. it is configured for all the UEs in the cell to reduce the overall load of the system. When the number of UEs in the cell and the number of UE service types are large, for example, in an urban area and areas of Olympic stadiums, etc., the second way can be adopted and different periods are configured Transmission cycling of the SR for the UEs according to the user level and service level of each UE in the cell to improve the configuration flexibility of the SR, make full use of the limited resources of the SR and to reduce the delay of the service.

In particular, the higher the user level of the UE in the cell, the shorter transmission period of the SR can be assigned to the UE; the shorter the time delay required by the UE service level in the cell, the shorter transmission cycle period of the SR can be assigned.

In step 202, the base station determines an uplink substructure for the transmission of the RS in the transmission cycling period of the SR.

In this step, different ways can be adopted to determine the uplink substructure for the transmission of the SR for FDD systems and TDD systems.

In an FDD system, all uplink substructures of the transmission cycling period of the SR can be used for transmission of the SR. For example, if the transmission cycling period of the SR is 10 ms, the 10 uplink substructures in the transmission cycling period of the SR can be used for transmission from the SR and can be assigned to different UEs for transmission of the SR. the R. The substructure lags of the uplink substructures can be values between 0 and 9, therefore 4 bits are needed to identify the 10 uplink substructures. If the transmission cycling period of the SR is 20 ms, the 20 uplink substructures in the transmission cycling period of the SR can be used for the transmission of SR and the substructure lags of the uplink substructures they can be values between 0 and 19, therefore 5 bits are needed to identify the substructure lags of the uplink substructures.

For an FDD system, some of the uplink substructures in the transmission cycling period of the SR can be used for transmission of the SR to reduce the number of bits needed to identify substructure lags. Preferably, one in each N uplink substructures in the transmission cycling period of the SR can be used for the transmission of the SR, wherein N is a pre-configured number. For example, if the transmission cycle period of the SR is 10 ms, an uplink substructure of each two uplink substructures can be selected for transmission of the SR and only 3 bits are needed to identify the substructure lags of the 5 uplink substructures for the transmission of the SR.

In a TDD system, the candidate substructures are configured in advance based on all the transmission cycles of the SR and the location indexes of the substructures of the candidate substructures are configured. The base station selects the uplink substructure for transmission of the SR from the candidate substructures according to the current configuration of the relationship between uplink to downlink intervals and the transmission cycle period of the UE SR. The candidate substructures are all uplink substructures that can possibly be used for the transmission of the SR.

In order to ensure that a UE has sufficient opportunity to send an uplink SR, resources are reserved as much as possible in a transmission cycle period of the SR. In In extreme cases, resources must be reserved for all uplink substructures, that is, all possible uplink substructures are the candidate substructures.

For example, in different configurations of interval relationships in a structure, all the uplink substructures are substructures 2, 3, 4, 7, 8, 9 and if the transmission cycle period of the SR of a certain SR is e 10ms, the candidate substructures and substructure lags of the candidate substructures can be: CUADR0 1 In the above table, substructure lags list all candidate substructures, substructure location indexes indicate substructure lags by using 3 bits. If the SR transmission cycling period is 20 ms, the maximum number of available substructure lags is 12 which requires at least 4 bits. If the transmission period of SR transmission is longer, more bits will be needed.

The base station selects an uplink substructure for transmission of the SR from the candidate substructures configured in advance according to the relationship between uplink to downlink intervals and the SR transmission cycle of the UE. For example, the SR transmission cycling period is 10-ms, and the configuration of the candidate substructures is as shown in Table 1. Under different relationship time configurations between uplink and downlink intervals, substructures uplink for SR transmission are selected from the current uplink substructures. All current uplink substructures can be selected for SR transmission.

Accordingly, the step of determining the uplink substructure for SR transmission has been completed. In this step, only the uplink substructure that can be used for SR transmission is determined. It is determined which uplink substructure is assigned to each UE, when the resource index has been determined.

The SR resources available in a cell are definitive, different UEs reuse preconfigured SR resource indices, and therefore there is a correlation between the resource indices of the UEs and the actual physical resources. In the correspondence relationship, the resource indices of different UEs should not conflict with each other, and if the UE does not make use of the resources for a long time, SR resources can be released.

Specifically, the following steps can be performed.

In step 203, the base station determines the total number of SR resources available in each uplink substructure for SR transmission, ie N, according to the total amount of SR resources in the cell and the number of the uplink substructures for the transmission of RS in a period of SR transmission cycling.

In step 204, N resources are selected among SR resources not allocated SR in the cell, and assigned to the N UEs with one of the N resources allocated to one of the N UEs.

When the SR resources are allocated in accordance with steps 203 and 204, in order to allocate the appropriate programming resources for each-each UE; the SR resource index can be denoted by, ^ SRI is ^ e 'substructure lag of the SR, NID is the ID of the UE, T is the transmission cycle of SR of the UE, TV is all resources available from SR. That is, the SR resource index is a function of the substructure offset, the UE ID, the SR transmission cycling period and the total number of SR resources.

In a specific example, if the SR transmission cycle of all the UEs is 100 ms, the phase shifts of the uplink substructure are 2, 3, 7, 8, the number of the uplink substructures for the SR transmission is 4, the total number of RS resources available in the cell is 100, 25 SR resources can be allocated to each uplink substructure for SR transmission, 25 UEs can be assigned to each substructure, each UE corresponding to a resource index.

In step 205, the base station sends the SR transmission cycle determined for each UE, the SR resources allocated for the UE, the uplink substructure corresponding to the SR resources to the UE.

Specifically, the UE may be notified of the SR transmission cycling period through broadcast, system or upper layer signaling. Preferably, when the SR transmission cycling period is configured using the first configuration mode, the UE can be notified through the broadcast system, when the SR transmission cycling period is configured using the second configuration mode. , it is possible for each UE of the SR transmission cycling cycle through the upper layer signaling. In addition, the SR transmission cycling period can be sent directly after step 201, or it can be sent in this step together with the SR resources and substructure offset.

The sending of SR resources may specifically include: preconfiguring the resource indices corresponding to the SR resources available in the cell; send the resource index corresponding to the allocated SR resources to the UE.

In step 206, if the SR resources allocated to the UE are not used in a preconfigured period of time, the base station releases the unused SR resources.

In one embodiment of the present invention, in order to make full use of SR resources, if the UE does not use the index of allocated SR resources in a preconfigured time period, the SR resource index must be released . Specifically, the base station uses SR resources corresponding to the SR resource index as available SR resources that can be assigned to another UE in the following SR configuration.

Thus, the process for configuring the uplink SR according to one embodiment of the present invention is completed. As can be seen in the method, the embodiment of the present invention implements the configuration and sending of the SR transmission cycle in the LTE system, the substructure location and the SR resources, which completes the entire SR configuration , and solutions are provided based on the different characteristics of FDD systems and TDD systems.

In addition, in the system mentioned above, if the base station does not intend to allocate the SR resources for certain UEs, the SR transmission cycles of the UEs can be set as infinite so that the SR resources are not assign the UEs.

In the aforementioned embodiment of the present invention, the SR transmission cycling period and the uplink substructure corresponding to the SR resources are denoted, respectively, and then sent to the UE. Specifically, the number of bits to denote the SR transmission cycling period is determined according to the number of SR transmission cycling periods, and the indicators are configured accordingly. The uplink substructures for the SR transmission are denoted by the substructure location indicators, and a substructure location indicator is sent to the UE separately and is not sent together with the SR transmission cycling period. In fact, the SR transmission cycling period and the uplink substructure for the SR transmission can be denoted and sent to the UE as a whole. In this way, after receiving a joint index, the UE can directly determine the uplink substructure for the SR transmission allocated to the UE and the SR transmission cycling period. In the following, the manner of joint indexing will be described. As with the previous modes, an uplink substructure for the transmission of SR is identified by a substructure lag.

When the SR transmission cycling period and the substructure lag are jointly identified, all possible combinations of SR transmission cycling and substructure shifts, optional in a cycle period of SR transmission, can be listed one by one, and coded as joint indexes of cycle-substructure. When an SR transmission cycle is to be sent and a substructure offset, the joint cycle-substructure index can be sent directly to a UE corresponding to the SR transmission cycling period and the substructure offset.

Ways to configure the joint cycle-substructure indices may include the following.

According to the simplest way, all optional SR transmission cycling periods are listed. For example, there are 4 types of SR transmission cycling periods that are separated by 5 ms, 10 ms, 20 ms, respectively, and separated indicates that the cycle is infinite. Then all substructure lags are coded in all periods of SR transmission cycling and SR transmission cycling periods, the 5 ms cycle has 5 substructure lags, the 10 ms cycle has 10 substructure lags, the 20 ms cycle has 20 substructure phase shifts, the separation cycle has only one possibility, hence the number of all combinations of 4 SR transmission cycling periods and the substructure lags in the 4 cycling transmission periods of SR are 36. The 36 combinations of the SR transmission cycling periods and the substructure lags are coded together, and the joint cycle-substructure index for each combination is configured, so that the 36 combinations can be identified by 6. bits.

In the manner mentioned above, the number of bits occupied by the joint cycle-substructure index is relatively large. In order to save system resources, the following ways can be adopted to reduce the number of bits occupied by the joint cycle-substructure index.

Specifically, for an FDD system, one of each N uplink substructures in each type of SR transmission cycling period can be used for SR transmission, N is a preconfigured number. The uplink substructure offsets of the uplink substructures are then coded together for SR transmission in all periods of SR transmission cycling and the SR transmission cycling period. The joint cycle-substructure indexes are configured for any combination of the substructure lags of the uplink substructures for SR transmission and SR transmission cycling cycles.

Or, for a TDD system, the candidate substructures in the base station are configured for all possible periods of transmission SR transmission, as described in the previous modalities. Then all the candidate substructure lags are coded in the SR transmission cycling periods and the SR transmission cycling periods, and the joint cycle-substructure indexes are configured for all combinations of the substructure lags of the candidate substructures and the periods of transmission cycling of SR.

Of course, it is only one example in which the transmission cycle of SR and the substructure offset are coded together and the joint cycle-substructure indexes are uniformly configured. In practice, other ways of coding can be adopted to co-code the combinations.
