Description

Signal transmitting and receiving method and device, first node, second node and medium

Technical Field

The present application relates to the field of communications, and in particular, to a method and apparatus for transmitting and receiving a signal, a first node, a second node, and a medium.

Background

Machine Type Communication (MTC), also known as machine-to-machine (Machine to Machine, M2M), is a major application form of current-stage internet of things. MTC devices currently deployed on the market are mainly based on the global system for mobile communications (Global System of Mobile communication, GSM) system. In recent years, due to high spectrum efficiency of LTE (Long Term Evolution )/LTE-a (LTE-Advanced, subsequent evolution of LTE technology), more and more mobile operators select LTE/LTE-a as an evolution direction of a broadband wireless communication system in the future. LTE/LTE-A based MTC multi-class data services would also be more attractive.

Several technologies suitable for cellular-level internet of things (combo-Internet Of Things, C-IOT) are disclosed in third generation partnership project (3 rd Generation Partnership Project, 3 GPP) technical report TR45.820V200, with narrowband internet of things (Narrow band-Internet Of Things, NB-IOT) technology being the most attractive. NB-IOT systems focus on low complexity and low throughput radio frequency access technologies, with main research objectives including: improved indoor coverage, support for a large number of low throughput user devices, low latency sensitivity, ultra low device cost, low device power consumption, and network architecture.

The network may send pages to idle and connected state terminals (UEs). The paging procedure may be triggered by the core network for informing a UE to receive a paging request, or by the eNB (base station) for informing of an update of system information. The paging message is scheduled with physical downlink control information (Physical Downlink Control Channel, PDCCH) scrambled by a P-radio network temporary identity (Radio Network Temporary Identifier, RNTI) and transmitted on a physical downlink shared channel (Physical Downlink SHARED CHANNEL, PDSCH). The terminal detects the corresponding PDCCH at paging time (Paging Occasion, PO) so as to determine whether the PDSCH indicated by the PDCCH carries paging messages or not. Whether or not there is paging transmission, the terminal needs to blindly detect the PDCCH search space before determining whether there is a corresponding PDCCH, which wastes power of the terminal.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail hereinafter with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be arbitrarily combined with each other.

In an exemplary embodiment, fig. 1 is a schematic flow chart of a signal sending method provided by the present application. The method may be applicable in the case where the first node sends a narrowband reference signal to the second node. The method may be performed by a signaling device provided by the present application, which may be implemented in software and/or hardware and integrated on the first node.

As shown in fig. 1, the signal transmitting method provided by the application includes S110 and S120.

S110, determining a first subframe according to a first parameter and a first rule; wherein the first subframe is a subframe including a narrowband reference signal.

Wherein the first parameter may be a signaling related parameter, such as a parameter of a higher layer signaling configuration. The first rule may be a rule for determining the first subframe. The first subframe may be a subframe including NRS (narrow band REFERENCE SIGNAL ).

In the present application, the first node may determine a first subframe including NRS according to the first parameter and the first rule.

S120, the narrowband reference signal is sent in the first subframe.

Accordingly, after determining the first subframe including NRS according to the first parameter and the first rule, the first node may transmit the NRS signal in the first subframe.

The signal transmitting method provided by the application can realize that the first node determines the first subframe according to the first parameter and the first rule and transmits the NRS signal in the first subframe. The second node may also determine a first subframe according to the first parameter and the first rule to receive the NRS signal in the first subframe and prematurely suspend blind detection of the PDCCH using the received NRS signal.

The signal sending method provided by the application can determine the first subframe according to the first parameter and the first rule, and send the narrowband reference signal in the first subframe, thereby effectively saving the technical problem of power consumed when the second node detects the PDCCH.

The terms "first" and "second" and the like in this specification are used for distinguishing between different objects and not for describing a particular sequential order. Illustratively, the first node may be a base station and the second node may be a terminal.

On the basis of the above embodiments, modified embodiments of the above embodiments are proposed, and it is to be noted here that only the differences from the above embodiments are described in the modified embodiments for the sake of brevity of description.

In one example, the first parameter is a parameter of a higher layer signaling configuration; the first rule is that a second number of the first subframes is included in a first number of subframes; or the first rule is that the third number of radio frames includes the second number of the first subframes.

Specifically, the first parameter in the present application may be a parameter nB configured by higher layer signaling. The first rule may be: the X subframes include Y first subframes. Wherein X and Y may be positive integers of 0 or more. Alternatively, X may be a set value, such as 20 or 40, and Y may be 10 or 8. Or the first rule may also be: the Z radio frames include Y first subframes. Wherein Z and Y may be positive integers of 0 or more. Alternatively, Z has a value of 2 or 4 and Y has a value of 10 or 8.

In one example, the determining the first subframe according to the first parameter and the first rule includes: determining paging moments corresponding to the first subframes according to the first parameters; and determining the number of the first subframes corresponding to the paging moment according to the first rule.

And determining the paging moment corresponding to the first subframe according to the first parameter, wherein the determined paging moment can be the paging moment containing the first subframe, or the paging moment containing the first subframe in the part determined according to the offset in the third number of radio frames. The number of first subframes corresponding to paging occasions is determined according to the first rule, and the number of first subframes corresponding to each paging occasion may be the same or different.

In one example, the determining, according to the first parameter, a paging occasion corresponding to the first subframe includes: if the first parameter is smaller than or equal to a first preset value, each paging moment is the paging moment containing the first subframe; or if the first parameter is greater than the first preset value, determining the paging moment containing the first subframe according to a first offset.

Accordingly, when determining the paging occasion corresponding to the first subframe according to the first parameter, the first preset value corresponding to the first parameter may be used as a reference. Specifically, when the first parameter is less than or equal to a first preset value, each paging occasion may be a paging occasion including the first subframe; when the first parameter is greater than a first preset value, the paging occasion including the first subframe may be determined according to the first offset.

In one example, the determining the paging occasion including the first subframe according to the first offset includes: determining paging moments including the first subframe in the N continuous paging moments according to the first offset; the first offsets corresponding to the first M radio frames are different from the first offsets corresponding to the second M radio frames, M is a positive integer greater than or equal to 1, and N is a positive integer greater than or equal to 2.

Specifically, the first offset may indicate which paging occasions of the consecutive N paging occasions of the radio frame contain the first subframe. For example, when n=2, it may be determined that one paging occasion out of every 2 paging occasions of one radio frame includes the first subframe. The first offset corresponding to each M radio frames may be different.

In one example, the determining, according to the first rule, the number of the first subframes corresponding to the paging occasion includes: if the number of the paging occasions in the second number of subframes and the first number of subframes is a multiple relation, determining that each paging occasion in the first number of subframes corresponds to the same number of first subframes; or if the number of the paging occasions in the second number and the first number of subframes is a non-multiple relation, determining the number of the first subframes corresponding to the paging occasions in the first number of subframes according to the second offset.

In one example, the determining, according to the second offset, the number of the first subframes corresponding to the paging occasion in the first number of subframes includes: and determining the number of the first subframes corresponding to the paging moment in each radio frame in the first number of subframes according to the second offset.

Wherein determining the number of the first subframes corresponding to the paging occasions in each radio frame of the first number of subframes according to the second offset may include two modes. In one mode, the second offset may be a fixed value; in another mode, the second offset may be a non-fixed value.

In one example, the second offset is a fixed value; determining, according to the second offset, the number of first subframes corresponding to the paging occasion in each radio frame of the first number of subframes, including: for each wireless frame, determining a first wireless frame and a second wireless frame according to the value corresponding to the second offset; the number of the first subframes corresponding to the paging occasions in the first radio frame and the second radio frame is different.

Specifically, when the second offset is a fixed value, the first radio frame and the second radio frame may be determined for each radio frame according to the value corresponding to the second offset. For example, when the second offset takes a value of 1, the first radio frame may always be the first radio frame of every D radio frames. Or the second offset may also be a value corresponding to a fixed frame index, for example, a frame index of an even term or a frame index of an odd term, where D is a positive integer greater than or equal to 1.

In one example, the second offset is a non-fixed value; determining, according to the second offset, the number of first subframes corresponding to the paging occasion in each radio frame of the first number of subframes, including: for each radio frame, determining a third radio frame and a fourth radio frame according to the value corresponding to the second offset; and the number of the first subframes corresponding to the paging moment in the third radio frame is different from that of the first subframes corresponding to the paging moment in the fourth radio frame.

Specifically, when the second offset is not a fixed value, the third radio frame and the fourth radio frame may be determined for each radio frame according to the value corresponding to the second offset. The second offset is illustratively one radio frame at a time from the first radio frame for the third radio frame every D radio frames.

In one example, the determining the first subframe according to the first parameter and the first rule includes: if the first parameter is smaller than or equal to a second preset value, determining that the positions of the first subframe in each L wireless frames are the same in the L wireless frames; or if the first parameter is greater than a second preset value, determining that the position of the first subframe in the first L radio frames is different from the position of the first subframe in the second L radio frames; wherein L is a positive integer greater than or equal to 1.

Specifically, the determining the position of the first subframe in the first L radio frames and the position of the first subframe in the second L radio frames may include: the position of the first subframe in the second L radio frames is an offset of the position of the first subframe in the first L radio frames, wherein an offset value is a positive integer less than or equal to 10.

In one example, the determining the first subframe according to the first parameter and the first rule includes: if the first parameter is greater than a third preset value, the first subframe number is the same for every H radio frames for different values of the first parameter, wherein H is a positive integer greater than or equal to 1.

In an exemplary embodiment, the present application further provides a signal receiving method, and fig. 2 is a schematic flow chart of the signal receiving method provided by the present application. The method is applicable to the situation that the second node receives the narrowband reference signal sent by the first node, and can be executed by the signal receiving device provided by the application, and the signal receiving device can be realized by software and/or hardware and is integrated on the second node. Reference may be made to the above embodiments for details of this embodiment, which are not described herein.

As shown in FIG. 2, the signal receiving method provided by the application comprises S210-S220.

S210, determining a first subframe according to a first parameter and a first rule; wherein the first subframe is a subframe including a narrowband reference signal.

S220, the narrowband reference signal is received in the first subframe.

In the present application, the second node may determine a first subframe including NRS according to the first parameter and the first rule, and receive the NRS signal in the first subframe.

The signal receiving method provided by the application can determine the first subframe according to the first parameter and the first rule, and receive the narrowband reference signal in the first subframe, thereby effectively solving the technical problem of power consumption caused by blind detection of the PDCCH by the second node.

Specifically, the first offset may refer to which paging occasions among consecutive N paging occasions of the radio frame include the first subframe. For example, when n=2, it may be determined that one paging occasion out of every 2 paging occasions of one radio frame includes the first subframe. The first offset corresponding to each M radio frames may be different.

Specifically, when the second offset is a fixed value, the first radio frame and the second radio frame may be determined for each radio frame according to the value corresponding to the second offset. For example, when the second offset takes a value of 1, the first radio frame may always be the first radio frame of every D radio frames. Or the second offset may also be a value corresponding to a fixed frame index, such as a frame index of an even term or a frame index of an odd term.

An exemplary description of determining the first subframe according to the first parameter and the first rule is provided below. Note that, in the schematic diagrams of the radio frames corresponding to the specific examples below, the number numbers corresponding to the bold fonts indicate the first subframe, that is, the NRS subframe. The number with a character border indicates the start subframe of the PO.

Fig. 3 is a schematic structural diagram of a radio frame according to the present application. In one specific example, assume that the first parameter nB is equal to 2T, where T represents a DRX (Discontinuous Reception ) sequential cycle. The first rule is: 40 There are at least 8 (second number Y) NRS subframes within the (first number X) subframes, assuming a first preset value of 2T.

Since nB < = 2T (first preset value), each PO has a corresponding NRS subframe. Since Y is equal to the determined number of POs b=8 within X subframes, the number of NRS subframes corresponding to each POs is the same. Since the number of POs is b=8, m=1, n=0, assuming that M is defined as the first M NRS subframes of the first 10 subframes of PO and N is defined as the first N subframes of PO. As shown in fig. 3, the POs on the sub-frame 4 and the sub-frame 9 in each radio frame corresponds to the NRS sub-frame including the sub-frame 4 and the sub-frame 9 in the previous radio frame.

Fig. 4 is a schematic structural diagram of a radio frame according to the present application. In one specific example, assume that the first parameter nB is equal to 2T, where T represents the DRX sequential cycle. The first rule is: 40 There are at least 10 (second number Y) NRS subframes within the (first number X) subframes, assuming a first preset value of 2T.

Since nB < = 2T (first preset value), each PO has a corresponding NRS subframe. Since Y is greater than the determined number of POs in X subframes b=8, there are 2 NRS subframes for POs in 1 radio frame out of every 4 radio frames, which may be referred to as a first radio frame, and the remaining 3 radio frames may be referred to as a second radio frame. As shown in fig. 4, a radio Frame #k+1 is a first radio Frame, and frames # K, frame #k+2 and #k+3 are second radio frames. M=2, n=0 corresponding to PO in the first radio frame, m=1, n=0 corresponding to PO in the second radio frame; let M be defined as the first M NRS subframes of the first 10 subframes of PO and N be defined as the first N subframes of PO start. As shown in fig. 4, NRS subframes corresponding to PO on subframe 4 in the first radio Frame #k+1 are subframe 4 and subframe 5 in the radio Frame #k; the NRS subframes corresponding to PO on subframe 9 are subframe 9 in radio Frame #k and subframe 0 in radio Frame #k+1. The NRS subframes of the POs on subframe 4 and subframe 9 in the remaining second radio frame are both subframe 4 and subframe 9 in the previous radio frame. Wherein the position of the first radio frame in every 4 radio frames may be determined by a second offset, wherein the second offset is:

The second offset is a fixed value. For example, the first radio frame is always the first of every 4 radio frames; or alternatively

The second offset is a non-fixed value. That is, the offset value of the first radio frame is different in every 4 radio frames. Fig. 5 is a schematic diagram of an effect of determining a first radio frame according to the present application, and in a specific example, as shown in fig. 5, offset values of the first radio frame in every 4 radio frames are 0, 1, 2, and 3.

Fig. 6 is a schematic structural diagram of a radio frame according to the present application. In one specific example, assume that the first parameter nB is equal to 2T, where T represents the DRX sequential cycle. The first rule is: 20 There are at least 8 (second number Y) NRS subframes within the (first number X) subframes. Assume that the first preset value is 2T.

Since nB < = 2T (first preset value), each PO has a corresponding NRS subframe. Since Y is equal to 2 times the determined number of POs b=4 within X subframes, the number of NRS subframes corresponding to each POs is the same. Since the number of POs is b=4, m=2, n=0, assuming that M is the first M NRS subframes of the first 10 subframes of POs, N is the first N subframes where PO starts. As shown in fig. 6, NRS subframes corresponding to PO on subframe 4 in radio Frame #k+1 are subframe 4 and subframe 5 in radio Frame #k, and NRS subframes corresponding to PO on subframe 9 in radio Frame #k+1 are subframe 9 and subframe 0 in radio Frame #k.

In one specific example, assume that the first parameter nB is equal to 2T, where T represents the DRX sequential cycle. The first rule is: 20 There are at least 10 (second number Y) NRS subframes within the (first number X) subframes, assuming a first preset value of 2T.

Since nB < = 2T (first preset value), each PO has a corresponding NRS subframe. Since Y is greater than 2 times the determined number of POs in X subframes b=4, there are 3 NRS subframes for POs in 1 radio frame out of every 2 radio frames, which may be referred to as a first radio frame, and another radio frame may be referred to as a second radio frame. As shown in fig. 7, a radio Frame #k+1 is a first radio Frame, and a Frame #k is a second radio Frame. M=3, n=0 corresponding to PO in the first radio frame, m=2, n=0 corresponding to PO in the second radio frame; let M be defined as the first M NRS subframes of the first 10 subframes of PO and N be defined as the first N subframes of PO start. As shown in fig. 4, NRS subframes corresponding to PO on subframe 4 in the first radio Frame #k+1 are subframe 4, subframe 5, and subframe 6 in the radio Frame #k; the NRS subframes corresponding to PO on subframe 9 are subframe 9 in radio Frame #k and subframes 0 and 1 in radio Frame #k+1. Wherein the position of the first radio frame in every 2 radio frames may be determined by a second offset, wherein the second offset is: :

the second offset is a fixed value. For example, the first radio frame is always the first of every 2 radio frames; or the frame index corresponding to the first radio frame is even; or the frame index corresponding to the first radio frame is odd. Or alternatively

The second offset is a non-fixed value. That is, the offset value of the first radio frame is different in every 2 radio frames. Fig. 8 is a schematic diagram of an effect of determining a first radio frame according to the present application, and in a specific example, as shown in fig. 8, an offset value of the first radio frame in each 2 radio frames is 0, 1, 0, 1.

Fig. 9 is a schematic structural diagram of a radio frame according to the present application. In one specific example, it is assumed that the first parameter nB is equal to T, where T represents a DRX sequential cycle. The first rule is: 40 There are at least 8 (second number Y) NRS subframes within the (first number X) subframes, assuming a first preset value of 2T.

Since nB < = 2T (first preset value), each PO has a corresponding NRS subframe. Since Y is equal to 2 times the determined number of POs b=4 within X subframes, the number of NRS subframes corresponding to each POs is the same. Since the number of POs is b=4, m=2, n=0, assuming that M is defined as the first M NRS subframes of the first 10 subframes of PO and N is defined as the first N subframes of PO. As shown in fig. 9, the NRS subframe corresponding to PO on subframe 9 in each radio frame is subframe 9 in the previous radio frame and subframe 0 in the present radio frame.

Fig. 10 is a schematic structural diagram of a radio frame according to the present application. In one specific example, it is assumed that the first parameter nB is equal to T, where T represents a DRX sequential cycle. The first rule is: 40 There are at least 10 (second number Y) NRS subframes within the (first number X) subframes. Assume that the first preset value is 2T.
