Of course, they are not limited to being applied to 5G communication systems. For example, they can also be applied to subsequent evolved communication systems. , Or the fourth generation (4 ^th generation, 4G) communication system, etc.

Please refer to FIG. 2. FIG. 2 is a flowchart of a method for determining an antenna port according to an embodiment of the present disclosure. As shown in FIG. 2, the method includes the following steps:

Step 201: Determine an antenna port set corresponding to each TCI state among multiple TCI states, where each TCI state has a corresponding relationship with the antenna port set;

Step 202: Determine the antenna port of each antenna port set according to the first value in the antenna port configuration, where the first value is used to indicate the antenna port of each antenna port set.

Among them, the above multiple TCI states may be configured by the network-side device to the terminal. Of course, this is not limited. For example, it may also be requested by the terminal or configured by the terminal itself.

In addition, in the embodiments of the present disclosure, one TCI state may correspond to one TRP, or may correspond to one beam in one TRP.

The above-mentioned respective TCI states and antenna port sets have a correspondence relationship that can be configured in advance, for example, a fixed correspondence relationship, or dynamically indicated, and one TCI state corresponds to one antenna port set.

In addition, in the embodiments of the present disclosure, the number of antenna ports included in different antenna port sets may be the same or different. For example, TCI state 0 corresponds to port set (0, 1), and TCI state 1 corresponds to port set (0).

The above-mentioned antenna port configuration may be pre-configured by the network-side device for the terminal, or may be agreed upon by a protocol, and the above-mentioned antenna port configuration may be a DMRS table (DMRS table), or other forms of port configuration. One value indicates the antenna port union, and the first value indicates the antenna port of each antenna port set.

The above-mentioned first value may be one of at least one value (for example: one of the values in the tables provided in the embodiment of the present disclosure) of the above-mentioned antenna port configuration, and the first value It may be indicated in the transmitted control information, for example, the network side device sends control information to the terminal, and the control information includes the above-mentioned first value, for example, the above-mentioned first value is indicated by the DMRS allocation indication of the control information.

The above-mentioned antenna port indicating the antenna port sets may be, the above-mentioned first value is used to indicate the antenna ports of multiple antenna port sets, and the multiple antenna port sets include the antenna port sets determined in step 201. For example, the first value indicates that the first antenna port set is (0, 1), and the second antenna port set is (0).

Since the above-mentioned first value can indicate the antenna port of each antenna port set, the antenna port of each antenna port set can be determined directly according to the first value in the antenna port configuration, where each antenna port set may refer to step 201 The set of determined antenna ports.

In the embodiments of the present disclosure, through the above steps, the corresponding antenna port sets can be determined for multiple TCI states to support multiple TCI state transmission, that is, there is no need to restrict multiple TRPs or panels to use the same number of layers for transmission. , Allowing multiple TRPs or panels to use different layers for transmission, which will not limit the total number of layers that can be used, thereby improving the frequency band utilization of the communication system.

Further, after the antenna ports of each antenna port set are determined, each TCI state may be used for transmission, where each TCI state uses the antenna port of the respective antenna port set for transmission when transmitting. Since multiple TCI states can be used for transmission, the transmission performance can be improved.

It should be noted that the foregoing antenna port determination method provided in the embodiments of the present disclosure may be applied to a communication device, and the communication device may be a terminal or a network side device.

It should be noted that in the embodiment of the present disclosure, the timing relationship between step 201 and step 202 is not limited. For example, as shown in FIG. 2, step 201 is performed first and then step 202 is performed, or step 201 and step 202 can be performed simultaneously. Execute, or execute step 202 first and then execute step 201, for example: first determine the antenna port of each antenna port set, and then determine the antenna port set corresponding to each TCI state.

As an optional implementation manner, the first value is also used to indicate a union of antenna ports, and the union of antenna ports includes antenna ports in the antenna port sets.

Wherein, the above-mentioned first value is used to indicate the antenna port union. The first value corresponds to one antenna port union. For example, the first value is used to indicate the DMRS antenna port (abbreviation: DMRS port(s)). These DMRS antennas The port is the union of the aforementioned antenna ports. For example: the first value indicates that the antenna port union (may be called DMRS port(s)) is (0,1), and indicates that the first antenna port set is (0,1), and the second antenna port set is (0 ).

The foregoing antenna port union includes the antenna ports in the antenna port sets. The union of the antenna ports in the antenna port sets may be the antenna port union, or it may be the antenna ports in the antenna port sets. The union of is part of the antenna ports of the aforementioned union of antenna ports.

Optionally, the aforementioned multiple TCI states include a first TCI state and a second TCI state, the antenna port set corresponding to the first TCI state is the antenna port union, and the antenna port corresponding to the second TCI state The set is a subset of the union of the antenna ports.

The above-mentioned multiple TCI states may include one or more first TCI states and one or more second TCI states.

The antenna port set corresponding to the first TCI state is the antenna port union set, which may be that, among the port sets corresponding to each TCI state, the antenna port set corresponding to the TCI state with the largest number of ports includes the above multiple TCI states The set of ports corresponding to all TCI states. For example, the foregoing antenna port union is (0, 1), TCI state 0 corresponds to port set (0, 1), and TCI state 1 corresponds to port set (0).

For ease of description, in the embodiments of the present disclosure, the maximum number of DMRS antenna ports corresponding to each TCI state is recorded as R=R.

In this implementation manner, it is possible to configure TCI states with different numbers of antenna ports to improve transmission flexibility, adapt to requirements of different services and scenarios, and further improve overall frequency band utilization.

As an optional implementation manner, the frequency domain resources corresponding to the multiple TCI states do not overlap; or

For example, in a time division multiplexing (TDM) transmission scheme, the time domain resources corresponding to multiple TCI states do not overlap. In a frequency division multiplexing (FDM) transmission scheme, multiple TCIs The frequency domain resources corresponding to the state do not overlap. In the TDM+FDM transmission scheme, the time domain and frequency domain resources corresponding to multiple TCI states do not overlap.

In this embodiment, since the resources corresponding to the multiple TCI states do not overlap, the transmission performance will be better when the multiple TCI states are used for transmission.

Of course, this is not limited. For example, when a specific transmission scheme is specified on the network side, such as a TDM, FDM, or TDM+FDM transmission scheme, the same method can be used to determine the antenna port set corresponding to each TCI state and each antenna The antenna port of the port collection.

As an optional implementation manner, each TCI state has a one-to-one correspondence with the antenna port set.

Among the above-mentioned multiple TCI states, there may be some TCI states corresponding to the same antenna port set. Of course, different TCI states may also correspond to different antenna port sets.

Among them, the above one-to-one correspondence can be fixed or dynamically indicated, for example:

Each TCI state has a fixed one-to-one correspondence with the antenna port set; or

For example: In a fixed relationship, TCI state 0 is mapped to the first port set, and TCI state 1 is mapped to the second port set;

In the dynamic relationship, the corresponding relationship between the port set and the TCI state depends on the value in the antenna port configuration (e.g. DMRS table). For example, for the above first value (e.g. value A), TCI state 0 is mapped to the first TCI state 1 is mapped to the second port set; for another value (for example: value B), TCI state 0 is mapped to the second port set, and TCI state 1 is mapped to the first port set.

The above fixed relationship can save the overhead of antenna port configuration, and the one-to-one correspondence dynamically indicated by the above first value can improve the flexibility of antenna port configuration.

As an optional implementation manner, the first part of the value in the above antenna port configuration is used to indicate the antenna port union, the antenna port indicating the set of multiple antenna ports, and the antenna port set corresponding to the TCI state, the antenna The second part of the port configuration is used to indicate the antenna port set.

Among them, the above-mentioned first part of the value may be one or more values in the antenna port configuration, and each value in the first part of the value may indicate the antenna port union, the antenna port of the multiple antenna port set, and the corresponding TCI state Collection of antenna ports. The aforementioned first partial value may be one or more values in the antenna port configuration, and each of the second partial values indicates a set of antenna ports (may be referred to as DMRS port(s)). It should be noted that in the embodiments of the present disclosure, the collective antenna ports indicated by the second partial value may no longer be divided into subsets.
