FIG. 1 shows a schematic structural diagram of a wireless communication system to which an embodiment of the present application can be applied. The wireless communication system includes a terminal 11 and a network-side device 12 . The terminal 11 may also be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 may be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital computer Assistant (Personal Digital Assistant, PDA), handheld computer, netbook, ultra-mobile personal computer (ultra-mobile personal computer, UMPC), mobile Internet device (Mobile Internet Device, MID), wearable device (Wearable Device) or vehicle-mounted device (VUE), pedestrian terminal (PUE) and other terminal-side devices, wearable devices include: smart watches, bracelets, headphones, glasses, etc. It should be noted that, the embodiment of the present application does not limit the specific type of the terminal 11 .

The resource determination method and apparatus provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

In a communication system, the network configures the terminal with BWP and/or carrier for data transmission. The bandwidth of the terminal can change dynamically.

Fig. 2 is a schematic diagram of a BWP configuration provided by an embodiment of the present application. As shown in Fig. 2, at the first moment, the service volume of the terminal is relatively large, and the system configures a large bandwidth (BWP1) for the terminal; at the second moment, the service volume of the terminal Small, the system configures a small bandwidth (BWP2) for the terminal to meet the basic communication needs; at the third moment, the system finds that there is a wide range of frequency selective fading within the bandwidth where BWP1 is located, or resources are relatively scarce within the frequency range where BWP1 is located , so a new bandwidth (BWP3) is configured for the terminal.

Each BWP is not only different in frequency and bandwidth, but also can correspond to different configurations. For example, the subcarrier spacing, CP type, and SSB (PSS/SSS PBCH Block) period of each BWP can be configured differently to adapt to different services.

There are four main technical advantages of BWP:

1. The terminal does not need to support the full bandwidth, but only needs to meet the minimum bandwidth requirements, which is conducive to the development of low-cost terminals;

2. When the terminal traffic is not large, the terminal can be switched to low-bandwidth operation, which can significantly reduce power consumption;

3. The communication technology is forward compatible. When a new technology is added to the communication system, the new technology can be directly run on the new BWP, which ensures the forward compatibility of the system;

4. Adapt to business needs and dynamically configure BWP for business.

In addition, in the communication system, the uplink and downlink configuration can be based on the granularity of symbols, and the configuration is more flexible. The specific configuration process is as follows:

(1) First configure the cell semi-static uplink and downlink configuration;

The upper layer provides the parameter TDD-UL-DL-ConfigurationCommon, which includes the reference subcarrier spacing u (reference SCS configuration) and pattern1, which also includes:

Slot configuration period (slot configuration period) P ms;

The number of downlink time slots Dslots (number of slots with only downlink symbols);

The number of downlink symbols Dsym(number of downlink symbols);

Uplink time slots Uslots (number of slots with only uplink symbols);

Usym(number of uplink symbols);

The configuration period P=0.625ms is only valid for 120kHz subcarrier spacing, P=1.25ms is only valid for 60 and 120kHz subcarrier spacing, and P=2.5ms is only valid for 30 60 and 120kHz subcarrier spacing. Then, a configuration period can be used to know how many time slots the period contains by using the formula S=P*2u. Of these time slots, the first Dslots time slots are downstream time slots, followed by Dsym downstream symbols, then Usym upstream symbols, and finally Uslots upstream time slots. After the uplink and downlink are configured in the S time slots, what remains is the flexible symbol X.

If the parameters are given to pattern1 and pattern2 at the same time, two different time slot formats can be configured continuously. The parameter format in pattern2 is similar to that in pattern1.

(2) Then configure the cell-specific uplink and downlink configuration;

If the high-level parameter TDD-UL-DL-ConfigDedicated is further provided on the basis of the configuration in (1), then this parameter can be configured with a flexible symbol configured by the parameter TDD-UL-DL-ConfigurationCommon. That is to say, the uplink and downlink symbols configured in (1) cannot be changed, but the flexible symbols can be rewritten by TDD-UL-DL-ConfigDedicated.

This parameter provides a series of slot configurations. For each slot configuration, the slot index slot index and symbol configuration are provided. For the slot specified by slot index, where:

If symbols=allDownlink, all symbols in this time slot are downlink;

If symbols=allUplink, all symbols in this time slot are uplink;

If symbols=explicit, the parameter nrofDownlinkSymbols first provides multiple downlink symbols;

That is to say, if it is explicit, then the parameter nrofDownlinkSymbols provides the number of downlink symbols, and nrofUplinkSymbols provides the number of uplink symbols. is provided, there are no upstream symbols. After the configuration is complete, if there are still remaining symbols, the remaining symbols are still flexible symbols X. The reference subcarrier spacing reference SCS configuration in (2) is the same as in (1).

The uplink and downlink configuration implemented by dynamic DCI is implemented through DCI format 2-0, or directly through the uplink and downlink data scheduling of DCI format 0-0 0-1 1-0 1-1. DCI format 2-0 is used exclusively for SFI indication. SFI mainly implements periodic frame structure configuration according to the time slot format that can be supported by a single time slot, that is, starting from receiving DCI format 2-0, it continues the physical downlink control channel monitoring period (Physical Downlink Control Channel, PDCCH monitoring period) slots , these slots are configured according to the indication of the time domain format indicator (slot format indicator, SFI) in the downlink control information (Downlink Control Information, DCI). The maximum number of formats supported by a single slot is 256, and 56 formats have been standardized. The slot format table of normal cp is shown in Table 1 below (slot format table of common cyclic prefix);
