Description

Information indicating method and related equipment

Technical field

The present application relates to the field of communications technologies, and in particular, to a method for resource allocation and related devices.

Background technique

Machine type communication (MTC) refers to the acquisition of information about the physical world by deploying various devices with certain sensing, computing, execution, and communication capabilities, and realizes information transmission, coordination, and processing through the network. The interconnection of things, things and things. Currently, long term evolution (LTE) versions of Rel (release)-12, Rel-13, Rel-14, and Rel-15 can support MTC services.

The resources of the LTE system are divided into subcarriers in the frequency domain, divided into subframes in time, and one subframe includes two slots. When the subcarrier spacing is 15 kHz, one physical resource block (PRB) contains 12 subcarriers in frequency, and is 1 slot in time.

In LTE Rel-13, the user equipment (UE) capable of supporting the MTC service is a bandwidth-reduced low-complexity UE (BL UE) or a coverage enhancement UE (CE UE). ). Its maximum supported transmit and receive bandwidth is 1.4MHz and includes a narrowband. A narrow band contains a frequency width of six consecutive PRBs in frequency.

LTE Rel-13 provides two coverage enhancement modes for coverage enhanced UEs, namely, coverage enhancement mode A (CE mode A) for smaller coverage enhancement levels and coverage enhancement mode B for larger coverage enhancement levels ( CE mode B). In order to enable the MTC to support a higher data rate, in LTE Rel-14, the bandwidth that the UE performing the MTC service can support for transmitting the service data is expanded. In CE mode A, the physical uplink shared channel (PUSCH) bandwidth supported by the UE is extended to 5 MHz. The PUSCH is used to carry uplink data of the UE.

The LTE system allocates frequency domain resources used by the PUSCH through downlink control information (DCI). The DCI is sent by the base station to the UE. For a BL/CE UE, the DCI is carried by a physical downlink control channel (MPDCCH) of a device type communication. In Rel-14 and its previous versions, the minimum unit for resource allocation for PUSCH is 1 resource block. In order to improve the spectrum efficiency of the PUSCH, it is one of the effective technical means to allocate resources of less than 12 subcarriers for the PUSCH.

In Rel-14 and its previous versions, the resource allocation information in the DCI carried by the MPDCCH can only indicate the resource allocation with the granularity of the PRB. In order to enable the DCI carried by the MPDCCH to indicate the resource allocation of less than 12 subcarriers, a new design needs to be designed. Resource allocation method.

Functional handheld devices, computing devices or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, terminal devices in the Internet of Things, virtual reality devices, terminal devices in future 5G networks, or future evolved public land mobile networks A terminal device in a (public land mobile network, PLMN), a UE that performs MTC service, a BL UE, or a CE UE.

For example, FIG. 1 is a schematic diagram of a communication system provided by an embodiment of the present application. As shown in FIG. 1, the communication system may include seven network devices, which are a base station and UE1 to UE6. In the communication system, the base station transmits DCI to one or more of UE1 to UE6. The DCI is used to indicate resource allocation of PUSCH of one or more UEs in UE1 to UE6. Therefore, the network device involved in the embodiment of the present application may be a base station, and the terminal device may be any one of UE1 to UE6.

For example, as shown in FIG. 1, UE4 to UE6 may also constitute a communication system, in which UE5 may transmit DCI to one or more UEs of UE4 and UE6. The DCI is used to indicate resource allocation of PUSCH of one or more UEs in UE4 and UE6. Therefore, the network device involved in the embodiment of the present application may be the UE5, and the terminal device may be any one of the UE4 and the UE6.

The information indicating method and related equipment provided by the present application are described in detail below.

Referring to FIG. 2, FIG. 2 is a schematic flowchart diagram of a method for resource allocation according to an embodiment of the present application. As shown in FIG. 2, the method for resource allocation includes the following sections 201-203, where:

201. The network device determines downlink control information that is sent to the terminal device.

The network device may be a base station or a terminal device. For example, as shown in FIG. 1, when the network device is a base station, the terminal device is any one of UE1 to UE6. When the network device is the UE5, the terminal device is any one of the UE4 and the UE6. The PUSCH is used to carry uplink data of the terminal device.

The network device determines downlink control information, that is, the network device determines downlink control information that needs to be sent to the terminal device.

202. The network device sends the downlink control information to the terminal device.

203. The network device receives data sent by the terminal device on a resource allocated by the terminal device.

It should be noted that, in the embodiment of the present application, since the downlink control information includes the indication information and the resource allocation information, the network device may implement at least two possible implementations before sending the downlink control information to the terminal device. The method determines the indication information and the resource allocation information included in the downlink control information.

In a first possible implementation, the resource allocation information includes

The bit is taken as an example for explanation. And determining, by the network device, the resource information according to the first mode, or the resource allocation according to the second mode, determining the information in the downlink control information; and determining, by the network device, the resource in the downlink control information according to the resource allocated for the terminal device Allocating information; the network device transmitting the determined downlink control information to the terminal device; the network device receiving the data sent by the terminal device on the resource allocated for the terminal device.

For example, when the network device indicates that the terminal device performs resource allocation according to the first manner, the status of the indication information bit is 0, and when the network device indicates that the terminal device performs resource allocation according to the second manner, The status of the indication information bit is 1; or, when the network device indicates that the terminal device performs resource allocation according to the first manner, the status of the indication information bit is 1, when the network device indicates the terminal device When the resource allocation is performed according to the second mode, the state of the indication information bit is 0.

It can be seen that the network device determines the bit status of the indication information according to whether the terminal device performs resource allocation according to the first manner or the second mode.

For example, when the field for indicating resource allocation information includes 5 bits, the first one of the 5 bits serves as a bit indicating information.

Optionally, the performing resource allocation according to the first manner includes: the resource allocation information indicates a granularity allocated by using six subcarriers and/or one resource block as a resource, and the resource allocation information indicates only six subcarriers. a resource allocation of one or more of the two resource blocks, and the resource allocation according to the second mode includes: the resource allocation information indicates a granularity of resource allocation by using three subcarriers, and the The resource block allocation information indicates only the resource allocation of the three subcarriers.
