Description

Component carrier configuration method, user equipment and base station

technical field

The present invention relates to the communication field, in particular, to a component carrier configuration method, user equipment and a base station.

Background technique

In order to meet the growing demand for large bandwidth and high-speed mobile access, the Third Generation Partnership Projects (Third Generation Partnership Projects, 3GPP for short) launched the Long-Term Evolution advance (LTE-Advanced for short) standard. LTE-Advanced adopts a series of new technologies on the basis of LTE to expand the frequency domain and air domain to achieve the purpose of improving spectrum utilization and increasing system capacity. The carrier aggregation technology can aggregate two or more component carriers (Component Carrier, CC for short) to support a wider frequency band. A user equipment (User Equipment, referred to as UE) can simultaneously receive/send data on two or more component carriers, and can be configured to aggregate different numbers of component carriers with different bandwidths in the downlink/uplink.

The component carrier can use a carrier compatible with the LTE system, which is called a backward compatible carrier; the component carrier can also use a carrier that is not compatible with the existing LTE system, and this kind of carrier is called a non-backward compatible carrier. It is used by UEs of Release 10 and above; the component carrier may also not allow any UE to camp on the carrier, which is called an extended carrier.

For a connected UE, the base station does not allow the UE to receive system information on certain component carriers, such as Master Information Block (MIB for short), System Information Block 1 (SIB1 for short), SIB2 , or some radio resource configuration information, for example, Radio Resource Control (RRC) connection establishment message (RRC Connection Setup), RRC Connection Reestablishment message (RRC Connection Reestablishment), RRC Connection Reconfiguration message (RRC Connection Reconfiguration) , or, some component carriers do not provide the above information. In addition, in LTE, UE only works on one carrier, so there is no method for carrier addition/deletion. At present, in the LTE-A system, there is no solution for acquiring configuration information of component carriers and implementing adding, modifying or deleting component carriers.

The implementation process of the embodiment of the present invention will be described in detail below with reference to examples.

Example one

The UE in the connected state works on the downlink carrier CC_D1 (paired with the uplink carrier CC_U1), CC_D2 (paired with CC_U2), and CC_D3 (paired with CC_U3), wherein CC_D1 (CC_U1) is used as the serving cell, and other component carriers are used as resources. The TA is the same for all component carriers.

The UE receives an RRC connection reconfiguration message (RRCConnectionReconfiguration) at CC1, which includes information elements for adding/modifying resources and information elements for deleting resources.

FIG. 2 is a schematic diagram of adding/modifying a component carrier according to Example 1 of an embodiment of the present invention. Adding/modifying a component carrier will be described below with reference to FIG. 2 .

The identifier of the downlink carrier CC_D4 is included in the information element of adding/modifying resources, and currently the UE does not work on CC_D4, therefore, it is necessary to add a component carrier resource for the UE. Configure the frequency band, bandwidth, PHICH configuration information, PDSCH configuration information of CC_D4 according to the information included in the cell, the maximum number of consecutive receptions of bottom layer out-of-sync indications, the maximum number of consecutive bottom-layer synchronization indications received, and the duration of the out-of-sync indication timer . Since the TA of all component carriers is the same, it is not necessary to obtain the TA value through the random access process on CC_D4, and the configuration information of RACH and PRACH is not included in the information element. According to the uplink and downlink carrier pairing relationship included in the information element, it can be known that CC_D4 and CC_D2 share CC_U2, therefore, there is no need to additionally configure uplink CC information. If the uplink and downlink carrier pairing relationship included in the information element indicates that CC_D4 and CC_U4 are paired, but the UE does not work on CC_U4, an uplink CC needs to be added according to the configuration information carried in the information element. The information to be configured includes: carrier frequency , bandwidth, PUCCH configuration information, PUSCH configuration information, SRS configuration information, uplink power control configuration information, HARQ configuration information, DRX configuration information, etc. The above configuration can take effect immediately, and the UE can perform uplink and downlink data transmission with the base station on CC_D4/CC_U2.

Including the identifier of the downlink carrier CC_D2 in the information element of adding/modifying resources means modifying the resource of a component carrier for the UE. According to the information contained in the information element, if the freqBandIndicator is included, the indicated frequency band shall be applied; if the field indicating the bandwidth of the downlink CC (for example, dl-Bandwidth) is included, the bandwidth of the downlink CC indicated by the field shall be applied; if the field indicating the PHICH configuration is included information element (for example, phich-Config), then apply the PHICH configuration information indicated by the field; if it includes an information element indicating PDSCH configuration information (for example, PDSCH-ConfigCommon), then apply the PDSCH configuration information indicated by the information element; if it includes Indicates the field (for example, N310) that indicates the maximum number of times that the "out of synchronization" instruction from the bottom layer is continuously received, then the maximum value of the number of times that the "out of synchronization" instruction from the bottom layer is continuously received as indicated by the application field is applied; if the indication is included In the field of the maximum number of times of "synchronization" indications received from the bottom layer continuously (for example, N311), the maximum number of times indicated by the application field is continuously received from the bottom layer of "synchronization" indications; if an out-of-synchronization indication is included For the field of timer duration, the out-of-sync indication timer duration indicated by the field shall be used; if the information element/field indicating the pairing relationship between CC_D2 and the existing uplink CC (for example, CC_U1) is included, there is no need to increase the uplink CC, the above configuration Effective immediately, the UE can perform uplink and downlink data transmission with the base station on CC_D2/CC_U1. If the information element/field indicating the pairing relationship between CC_D2 and CC_U5 is included, add an uplink CC according to the configuration information carried in the information element. The process is the same as adding CC_U4. The above configuration takes effect immediately, and the UE can perform uplink and downlink with the base station on CC_D2/CC_U5 data transmission.

FIG. 3 is a schematic diagram of deleting a component carrier according to Example 1 of an embodiment of the present invention. The deletion of a component carrier will be described below with reference to FIG. 3 .

Including the identifier of the downlink carrier CC_D3 in the information element of resource deletion means that the resource of one component carrier is deleted. The UE deletes the configuration information of CC_D3. Since CC_U3 paired with CC_D3 has no pairing relationship with other downlink CCs, its configuration information can also be deleted accordingly. Of course, considering that the newly added downlink CC may be paired with CC_U3 in the subsequent process, or the existing downlink CC may be paired with CC_U3 due to the modification of the existing pairing relationship, the configuration information of CC_U3 can also be retained, so that in the subsequent process The signaling overhead and delay of configuring CC_U3 can be saved.
