Embodiment 1
[0046] This embodiment provides a method for expressing the UE's multipoint transmission capability, which is used to express the combination relationship of the UE with respect to the number of carriers and the number of simultaneously receiving sectors, so that in the above scenario where the network side configures resources for the UE, the UE can pass Appropriate signaling is used to send information about the number of frequency points of each sector it supports to the network. Only after the network side receives the information correctly, can it allocate appropriate radio resources to the UE, make reasonable configurations, and then run well. If the network can learn in advance the maximum number of downlink carriers supported by the UE in each sector, it can accurately configure resources when configuring resources for the UE, thus ensuring the maximum utilization of the capabilities supported by the UE.
[0047] First, you may need to define several basic variables: t...

[0054] Embodiment 2: Matrix representation
[0055] Taking a UE with a maximum of 8 carrier frequencies as an example, the following matrix capability of (MFS+1)×(MFS+1) is used to represent its capability range. As shown in Table 1, the horizontal axis represents the number of carrier frequencies used by one sector, and the vertical axis represents the number of carrier frequencies corresponding to another sector. For each unit in the matrix, 1 indicates whether the UE supports this scenario, and 0 indicates that it does not support it. Change the scene. For example, the black cells in the table indicate that the UE supports one sector to use one carrier frequency and the other sector to use five carrier frequencies while simultaneously receiving data.
[0056] Form 1:
[0057]
[0058] From the perspective of all the multipoint transmission support capabilities in the above table, the shown scenario indicates that the UE does not support the scenario where the number of...

[0071] Embodiment 3: classification representation
[0072] For the further expansion of MSS, if we simply use the method of expanding the matrix to a cube and performing a full arrangement, it will consume a lot of binary numbers, and its numbering is also more complicated. Therefore, it can be defined in the form of attribute fields .
[0073] The classification representation method in this embodiment is to use the number of sectors with the same frequency points as the first-level classification attribute. There are three cases where the number of frequency points is the same in each area, and the number of frequency points in the three sectors is different. Then, sub-attributes can be defined under each first-level classification attribute to indicate a more precise capability expression. This idea can also be further extended to the case of more sectors.
[0074] For the background of 3GPPRel12, an example is given below to illustrate the use of the matrix representat...
