Description

Terminal, network device and method for identifying carrier

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a terminal, a network device, and a method for identifying a carrier.

Background

Currently, the carriers defined by the standard include Legacy carriers and NCT (New Carrier Type) carriers, which in turn further include Non-stand alone NCT carriers and stand alone NCT carriers. The Non-persistent NCT Carrier cannot be operated alone, and must perform Carrier Aggregation (CA) processing with a Legacy Carrier or a persistent NCT Carrier, where the persistent NCT Carrier is further added to the Non-persistent NCT Carrier and supports a broadcast mechanism to acquire system information and mobility of a terminal (UE).

In the prior art, the UE may identify the type of the carrier according to the relative location information of the PSS (Primary Synchronization Signal) and the SSS (Secondary Synchronization Signal). For example: in an FDD (Frequency Division Multiplexing) system, the PSS of a Legacy carrier is located on the last OFDM (Orthogonal Frequency Division Multiplexing) symbol of the 0 th and 5 th subframes, and the SSS is located on the second last OFDM symbol of the 0 th and 5 th subframes. By changing the relative position of PSS and SSS, for example: the PSS and SSS are separated by one OFDM symbol to enable the UE to identify Legacy carriers and NCT carriers. Although the UE can distinguish the Legacy carrier from the NCT carrier according to the detection result of the synchronization signal, it cannot further distinguish the Non-standard NCT carrier from the standard NCT carrier.

The network device 102 disclosed in this embodiment includes a first obtaining unit 103 and a sending unit 104, as shown in fig. 2. The first obtaining unit 103 obtains indication information of a neighboring cell carrier type from an OAM (Operation, administration, and Maintenance) entity or from a neighboring cell base station through an X2 interface, and the sending unit 104 obtains the indication information of the neighboring cell carrier type from the first obtaining unit 103 and sends the indication information of the neighboring cell carrier type to the terminal 101. The neighboring base station refers to a base station whose deployment location has a neighbor relation with the network device 102. Optionally, the network device 102 is a base station.

In this embodiment, the network device 102 communicates with the terminal through a cell of the network device 102. That is, transmitting section 104 of network device 102 transmits the indication information of the neighbor cell carrier type to terminal 101 through the cell. The following describes in detail how the network device 102 sends the indication information of the neighbor carrier type to the terminal 101.

In the cell reselection process, the sending unit 104 of the network device 102 sends the indication information of the neighboring cell carrier type to the terminal 101 through the system information broadcast by the cell in which the terminal 101 resides. Furthermore, transmitting section 104 of network device 102 also transmits transmission subframe information of the reduce CRS to terminal 101 using the system information.

The types of the adjacent region carrier comprise a Legacy carrier, a Non-standard NCT carrier and a standard NCT carrier.

In this embodiment, the terminal 101 performs cell selection and camps on the selected cell, and the obtaining unit 105 reads system information of the camped cell. In the cell reselection process, the obtaining unit 105 of the terminal 101 obtains the indication information of the neighboring cell carrier type through the system information broadcasted by the camping cell.

Or, if the indication information of the neighboring cell carrier type does not exist in the system information for reselecting the intra-frequency cell, the identifying unit 106 of the terminal 101 identifies that the carriers belonging to all intra-frequency neighboring cells of the cell where the terminal 101 resides are standard anonenct carriers.

Or, if there is indication information of a neighboring cell carrier type associated with a physical cell identifier in the system information for intra-frequency cell reselection, the identifying unit 106 of the terminal 101 identifies that a carrier to which a cell indicated by the physical cell identifier belongs is a Non-standard NCT carrier or a Legacy carrier. Wherein, the indication information of the carrier type associated with the physical cell identifier occupies 1bit, for example: 0 indicates that the carrier to which the cell indicated by the physical cell identifier belongs is a Non-standard NCT carrier, and 1 indicates that the carrier to which the cell indicated by the physical cell identifier belongs is a Legacy carrier, or vice versa.

Alternatively, if the physical cell identifier is not associated with the indication information of the neighboring cell carrier type in the system information for intra-frequency cell reselection, the identifying unit 106 of the terminal 101 identifies that the carrier to which the cell indicated by the physical cell identifier belongs is a standard NCT carrier.

Identification section 106 of terminal 101 performs RRM (Radio Resource Management) measurement based on the transmission subframe information.

When the inter-frequency cell is reselected, the obtaining unit 105 of the terminal 101 obtains the indication information of the neighboring cell carrier type through the system information for inter-frequency cell reselection broadcast by the camped cell, where the system information includes at least one of the following situations.

If the carrier frequency is not associated with the indication information of the neighboring cell carrier type in the system information for inter-frequency cell reselection, the identification unit 106 of the terminal 101 identifies that the carriers belonging to all cells under the carrier frequency are Legacy carriers.

Alternatively, if the system information for inter-frequency cell reselection includes indication information of a neighboring cell carrier type associated with a carrier frequency and a physical cell identifier, the identifying unit 106 of the terminal 101 identifies that a carrier to which a cell corresponding to the physical cell identifier belongs is a standard NCT carrier or a Non-standard NCT carrier under the carrier frequency.
