Description

Information indication method and related equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information indication method and related devices.

Background

Machine type communication (machine type communication, MTC) refers to the process of obtaining information of the physical world by deploying various devices with certain sensing, computing, executing and communication capabilities, and implementing information transmission, coordination and processing through a network, so as to implement interconnection between people and objects and between objects and objects. Release-12, rel-13, rel-14, rel-15 versions of the current long term evolution (long term evolution, LTE) are capable of supporting MTC traffic.

The resources of the LTE system are divided into subcarriers in the frequency domain, and are divided into subframes in time, one subframe containing 2 slots. When the subcarrier spacing is 15kHz, one physical resource block (physical resource block, PRB) contains 12 subcarriers in frequency, 1 slot in time.

In LTE Rel-13, a User Equipment (UE) capable of supporting MTC services is a bandwidth reduced low-complexity UE (BL UE) or coverage enhanced UE (coverage enhancement UE, CE UE). The maximum supportable transmission and reception bandwidth is 1.4MHz, and includes a narrow band. A narrowband contains the frequency width of 6 PRBs in succession in frequency.

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

The LTE system allocates frequency domain resources used for PUSCH by downlink control information (downlink control Information, DCI). The DCI is sent by the base station to the UE. For BL/CE UEs, the DCI is carried over a physical downlink control channel (MTC physical downlink control channel, MPDCH) for machine type communications. In Rel-14 and its previous versions, the smallest unit of resource allocation for PUSCH is 1 resource block. To improve the spectrum efficiency of PUSCH, allocating resources smaller than 12 subcarriers for PUSCH is one of the effective technical means that may be adopted.

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 PRB as granularity, and in order to enable the DCI carried by the MPDCCH to indicate the resource allocation of less than 12 subcarriers, a new resource allocation method needs to be designed.

Wherein one resource block contains 12 subcarriers in frequency. In order to enable DCI to indicate resource allocation of less than 12 subcarriers, a new resource allocation method needs to be designed.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for allocating resources according to an embodiment of the present application. As shown in fig. 2, the method for allocating resources includes the following 201 to 203 parts, in which:

201. The network device determines downlink control information to be transmitted 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 UE 6. When the network device is UE5, the terminal device is either one of UE4 and UE 6. The PUSCH is used for carrying uplink data of the terminal device.

The network device determines downlink control information, i.e. the network device determines downlink control information to be sent to the terminal device.

202. The network equipment sends the downlink control information to the terminal equipment;

203. and the network equipment receives the data sent by the terminal equipment on the resources allocated to the terminal equipment.

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, before the network device sends the downlink control information to the terminal device, the network device may determine the indication information and the resource allocation information included in the downlink control information through at least two possible implementations as follows.

In a first possible implementation manner, the resource allocation information includes The bits are illustrated as examples. The network equipment determines indication information in the downlink control information according to whether the resource allocation is performed according to a first mode or a second mode; the network equipment determines resource allocation information in the downlink control information according to the resources allocated to the terminal equipment; the network equipment sends the determined downlink control information to the terminal equipment; and the network equipment receives the data sent by the terminal equipment on the resources allocated to the terminal equipment.

For example, when the network device instructs the terminal device to perform resource allocation according to the first mode, the state of the instruction information bit is 0, and when the network device instructs the terminal device to perform resource allocation according to the second mode, the state of the instruction information bit is 1; or when the network equipment instructs the terminal equipment to perform resource allocation according to the first mode, the state of the instruction information bit is 1, and when the network equipment instructs the terminal equipment to perform resource allocation according to the second mode, the state of the instruction information bit is 0.

The visible network equipment determines the bit state of the indication information according to whether the indication terminal equipment performs resource allocation according to the first mode or the second mode.

For example, when the field for indicating the resource allocation information contains 5 bits, a first bit of the 5 bits is used as a bit of the indication information.

Optionally, the allocating resources according to the first mode includes: the resource allocation information indicates granularity of resource allocation by taking six subcarriers and/or one resource block, and the resource allocation information only indicates resource allocation of one or more of six subcarriers, one resource block and two resource blocks; the resource allocation according to the second mode includes: the resource allocation information indicates granularity of resource allocation with three subcarriers, and the resource block allocation information indicates only resource allocation of the three subcarriers.

Optionally, when the resource is allocated according to the first mode, the resource allocation information further includesA bit of>A bit indicates a narrowband index and the narrowband is made up of six consecutive resource blocks, wherein +.>Representing the number of uplink RBs corresponding to the system bandwidth, < + >>Representing a round up->Representing a downward rounding; the resource allocation information further comprises four bits, the 4 bits have 16 bit states, 6 bit states are included in the 16 bit states, and each bit state in the 6 bit states indicates that one resource block is allocated to the terminal equipment; and/or the 16 bit states further comprise 2 bit states, and each bit state in the 2 bit states indicates to allocate two resource blocks for the terminal device; and/or, 8 bit states are further included in the 16 bit states, and each bit state in the 8 bit states indicates that 6 subcarriers are allocated to the terminal device.

For example, whenIn the case of the resource allocation according to the first mode, the resource allocation information includes +.>Bits, the 3 bits are used to indicate one narrowband index, and the narrowband is composed of six consecutive resource blocks. / >

It can be seen that, when the resource allocation is performed according to the first mode, the resource allocation information is first passed throughBitsThe position of the narrowband where the allocated resource is located is indicated, and then the state of 16 is indicated by another 4 bits, wherein the state of 16 corresponds to the allocation state of 6 kinds of 1 resource blocks, the allocation state of 2 kinds of 2 resource blocks and the allocation state of 8 kinds of 6 sub-carriers.

Optionally, the narrowband includes six consecutive resource blocks of PRB n, PRB n+1, PRB n+2, PRB n+3, PRB n+4, and PRB n+5, and four bits in the resource allocation information indicate that allocated resources satisfy the mapping relationship of table 9 below; wherein, PRB m1, PRB m2, PRB m3 and PRB m4 are resource blocks which are notified to the terminal equipment by the network equipment through RRC or MAC CE; wherein n is an integer of 0 or more, n, n+1, n+2, n+3, n+4, and n+5 represent indexes of PRBs, m1 to m4 are integers of 0 or more, and m1, m2, m3, and m4 represent indexes of PRBs.

Optionally, four bits in the resource allocation information indicate that the allocated resources satisfy the mapping relationship of table 10 below.

By way of example, when PRB m1, PRB m2, PRB m3, PRB m4 are four PRBs in the narrowband, the PRB m1, PRB m2, PRB m3, PRB m4 are 4 PRBs, either contiguous or non-contiguous, of PRB n, PRB n+1, PRB n+2, PRB n+3, PRB n+4, and PRB n+5.
