Description

Information indication 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 a related device.

Background

Machine Type Communication (MTC) refers to acquiring information of a physical world by deploying various devices having certain sensing, computing, executing and communication capabilities, and implementing information transmission, coordination and processing through a network, thereby implementing interconnection of people and objects, and interconnection of objects and objects. Currently, the Release 12, Release 13, Release 14 and Release 15 versions of Long Term Evolution (LTE) can support MTC services.

The resources of the LTE system are divided into subcarriers in the frequency domain and into subframes in time, one subframe containing 2 slots. When the subcarrier spacing is 15kHz, one Physical Resource Block (PRB) contains 12 subcarriers in frequency and 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 a coverage enhancement UE (CE UE). Its maximum supportable transmit and receive bandwidth is 1.4MHz, comprising a narrow band. One narrow band contains a frequency width of 6 PRBs consecutively in frequency.

LTE Rel-13 provides two coverage enhancement modes for coverage enhanced UEs, namely coverage enhancement mode a (ce mode a) for smaller degrees of coverage enhancement and coverage enhancement mode b (ce mode b) for larger degrees 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. 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 transmitted by the base station to the UE. For BL/CE UEs, DCI is carried over a machine type communication physical downlink control channel (MPDCCH). 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, allocating resources smaller than 12 subcarriers to the 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 resource allocation with PRB as granularity, and in order to enable the DCI carried by the MPDCCH to indicate resource allocation with less than 12 subcarriers, a new resource allocation method needs to be designed.

For terminal equipment in coverage enhancement mode B, the existing LTE adopts DCI format 6-0B to schedule PUSCH, that is, the LTE adopts DCI format 6-0B to indicate information such as resource allocation, modulation and coding mode and the like of PUSCH.

In the existing DCI format 6-0B, the bit for resource block allocation indicates that the frequency resource of the allocated PUSCH includes a resource block greater than or equal to 1. Here, the resource block described herein is a physical resource block, i.e., PRB. In order to improve the spectrum efficiency of the PUSCH, the terminal device needs to be allocated frequency resources of the PUSCH smaller than 12 subcarriers, that is, frequency resources of the PUSCH allocated with the subcarrier as the minimum unit. Wherein one resource block contains 12 subcarriers in frequency. In order for DCI to indicate resource allocation of less than 12 subcarriers, a new resource allocation method needs to be designed.

Therefore, the embodiment of the present application provides a resource allocation method and related device, which can implement resource allocation of DCI indication smaller than 12 subcarriers.

The present application may also be applied to other communication systems as long as the communication system includes a resource allocation where an entity (i.e., a network device) needs to send DCI to indicate communication with another entity (i.e., a terminal device) that needs to interpret DCI in some way.

For example, the network device may be an evolved node B (eNB or eNodeB) in an LTE system, or a radio network controller in a Cloud Radio Access Network (CRAN), or may be an access network device in a 5G network, such as a gNB, or may be a small station, a micro station, a Transmission Reception Point (TRP), or may be an access network device in a relay station, an access point, or a future evolved Public Land Mobile Network (PLMN), and the like.

Alternatively, the network device may also be a terminal device, that is, the present application may be applied to a communication system, where the communication system includes a resource allocation that one terminal device needs to transmit DCI to indicate communication with another terminal device, and the another terminal device needs to interpret the DCI in some way. For example, a terminal device referred to herein may be an access terminal, a User Equipment (UE), a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile terminal, a user terminal, a wireless network device, a user agent, or a user equipment. The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in the internet of things, a virtual reality device, a terminal device in a future 5G network or a terminal device in a future evolved Public Land Mobile Network (PLMN), a UE performing MTC service, a BL UE or a CE UE, and the like.

For example, fig. 1 is a schematic diagram of a communication system provided in an embodiment of the present application. As shown in FIG. 1, the communication system may include 7 network devices, which are a Base station (Base station) and UEs 1-6. In the communication system, the base station transmits DCI to one or more of the UEs 1 to 6. The DCI is used to indicate PUSCH resource allocation for one or more of the UEs 1 to 6. Therefore, the network device in the embodiment of the present application may be a base station, and the terminal device may be any one of UE1 to UE 6.

For another example, as shown in fig. 1, UEs 4-6 may also form a communication system, and in the communication system, UE5 may send DCI to one or more of UE4 and UE 6. The DCI is used to indicate a resource allocation of a PUSCH for one or more of UE4 and UE 6. Therefore, the network device involved in the embodiment of the present application may be UE5, and the terminal device may be any one of UE4 and UE 6.

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

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for resource allocation according to an embodiment of the present disclosure. As shown in FIG. 2, the method for resource allocation includes the following parts 201-203:

201. the network device determines the downlink control information 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 UE 6. When the network device is UE5, the terminal device is any one of UE4 and UE 6. The PUSCH is used to carry uplink data of the terminal device.

The network device determines the downlink control information, that is, the network device determines the downlink control information that needs 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 distributed to the terminal equipment.

It should be noted that, in this 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 indication information and the resource allocation information included in the downlink control information may be determined by at least two possible implementation manners as follows.

In a first possible implementation manner, the resource allocation information includes

The bits are illustrated as examples. The network equipment determines the indication information in the downlink control information according to whether the resource allocation is carried out according to the first mode or the 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.

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

And the visible network equipment determines the bit state of the indication information according to the resource allocation of the indication terminal equipment in 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 method includes: the resource allocation information indicates the granularity of resource allocation by using six subcarriers and/or one resource block, and the resource allocation information only indicates the resource allocation of one or more of the six subcarriers, the one resource block and the two resource blocks; the resource allocation according to the second mode comprises: the resource allocation information indicates the granularity of resource allocation by using three subcarriers, and the resource block allocation information only indicates the resource allocation of the three subcarriers.

A bit, the

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

For example, when PRB m1, PRB m2, PRB m3, PRB m4 areFour PRBs in a narrow band, the PRB m1, PRB m2, PRB m3, PRB m4 being 4 PRBs that are continuous or discontinuous from among PRB n, PRB n +1, PRB n +2, PRB n +3, PRB n +4, and PRB n + 5.
