Detailed Description

So that the manner in which the features and technical contents of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the present invention will be rendered by reference to the appended drawings, which are included for purposes of illustration and not limitation.

Before describing embodiments of the present invention in detail, a brief description of the relevant contents of the NR system will be given.

Common channels and signals in the NR system, such as Synchronization Signal (Synchronization Signal) and broadcast channel, need to cover the whole cell by means of multi-beam scanning so that UEs in the cell can receive them. Multi-beam transmission of the SS is achieved by defining a set (burst set) of SS/Physical Broadcast Channels (PBCH). An SS burst set contains one or more SS/PBCH blocks. One SS/PBCH block is used to carry the synchronization signal and broadcast channel of one beam. Thus, one SS/PBCH burst set may contain synchronization signals for the same number of beams as the number of SS/PBCH blocks in the cell. The maximum number L of SS/PBCH blocks is related to the frequency band of the system: when the frequency of the system is at most 3GHz, the value of L is 4; when the frequency range of the system is 3GHz to 6GHz, the value of L is 8; when the frequency range of the system is 6GHz to 52.6GHz, the value of L is 64.

A schematic diagram of an SS/PBCH block (hereinafter referred to as SSB) is shown in fig. 1, and includes a Primary Synchronization Signal (PSS) of one symbol, a Secondary Synchronization Signal (SSs) of one symbol, and a New Radio Access Technology-Physical Broadcast CHannel NR-PBCH (New Radio Access Technology-Physical Broadcast CHannel) of two symbols.

All SS/PBCH blocks in the SS/PBCH burst set are sent in a time window of 5ms and are repeatedly sent in a certain period, and the sending period is configured by high-level parameter SSB-timing, wherein the sending period comprises 5ms, 10ms, 20ms, 40ms, 80ms, 160ms and the like.

The distribution diagram of SSBs under different subcarriers is shown in fig. 2; fig. 2 shows the timeslot distribution of SS/PBCH blocks in different subcarrier checking and frequency bands, where, for example, a subcarrier spacing of 15kHz, L being 4, one timeslot (slot) contains 14 symbols (symbol), and may carry two SS/PBCH blocks. The 4 SS/PBCH blocks are distributed in the first two slots within the 5ms time window. Wherein L is the maximum number of SSBs, and the number of actually transmitted SSBs may be smaller than L. And the network equipment informs the UE of the position of the actually sent SSB through system information in the form of bitmap.

The transmission of SSBs over unlicensed spectrum and unlicensed spectrum is briefly described below.

Unlicensed spectrum is a nationally and regionally divided spectrum that may be used for communication by radio devices, and is generally considered a shared spectrum, i.e., a spectrum that may be used by communication devices in different communication systems as long as the regulatory requirements set by the country or region on the spectrum are met, without requiring a proprietary spectrum license to be applied to the government. In order for various communication systems using unlicensed spectrum for wireless communication to coexist friendly on the spectrum, some countries or regions stipulate regulatory requirements that must be met using unlicensed spectrum. For example, in european regions, the communication device follows the principle of "Listen Before Talk" (LBT), that is, Before the communication device performs signal transmission on the unlicensed spectrum channel, it needs to perform channel sensing first, and only when the channel sensing result is that the channel is idle, the communication device can perform signal transmission; if the channel sensing result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot perform signal transmission. In order to ensure fairness, in one transmission, the duration of signal transmission by the communication device using the unlicensed spectrum Channel cannot exceed the Maximum Channel Occupancy Time (MCOT).

In NR systems, data transmission is achieved using NR techniques over unlicensed spectrum. In the transmission process of the SSB, since there is a possibility of LBT failure, the transmission time of the SSB defined in the NR may not be successful in transmitting the SSB. One improvement is to increase the sending opportunity of the SSB, define the sending time of a new SSB as an alternative; when the SSB cannot be transmitted at one transmission time due to LBT failure, the SSB is transmitted at an alternative transmission time. As shown in fig. 3, when LBT performed before the transmission time of SSB index 0 fails, channel sensing continues, and LBT performed before SSB index2 succeeds, the remaining SSBs are transmitted from SSB index2, and after SSB index 7 is transmitted, the SSB index 0 and SSB index1 that have not been successfully transmitted before are transmitted. Wherein the time actually transmitted by the SSB index 0 and the SSB index1 is the alternative transmission time. Depending on the moment the LBT succeeds, the actual transmission time of the SSB may be located at the initial transmission time or at an alternative transmission time. Fig. 3 is only used as a scheme for increasing the SSB transmission opportunity, and other alternatives exist, which are not described herein again.

Also, since there is a possibility of failure in LBT on the unlicensed spectrum, the transmission of the SSB may not be transmitted according to a predefined pattern (pattern); one improvement is to introduce multiple candidate locations for possible SSB transmissions within a time window. For example, for a frequency band below 6GHz, there are at most 8 indexes of the SSB, and the network device may notify the specific SSB transmission position of the UE through a bit map of 8 bits in a broadcast manner, where each bit represents whether an SSB is transmitted or not, so that the UE performs rate matching when receiving downlink transmission data. In the unlicensed spectrum, since the time when the right to use the channel is obtained is uncertain, the actual transmission position of the terminal SSB cannot be notified only by the semi-static system information. At this time, it is necessary to determine at which positions of the multiple candidate positions the SSB actually sends the SSB, so that the SSB performs rate matching when the UE receives downlink transmission data.

In consideration of uncertainty of obtaining the channel use right on the unlicensed spectrum, within a transmission window, the number Y of candidate positions of the SSBs configured by the network device is greater than the number X of SSBs actually sent by the network device. That is, for each Demodulation Reference Signal (DRS) transmission window, the network device may determine to transmit the SSB using X available candidate locations of the Y candidate locations according to a detection result of the LBT within the DRS transmission window, where locations of the X SSBs actually transmitted within different DRS transmission windows may be different. Therefore, it is necessary to consider how to indicate the location of the SSB actually transmitted within one DRS window. In NR transmission techniques over unlicensed spectrum below 6GHz, an improvement is that the maximum number of SSB transmissions is 8, and there are 64 candidate transmission locations within a time window.

As shown in fig. 5, an optional processing flow of the method for transmitting control information applied to a terminal device provided in the embodiment of the present invention includes the following steps:

step S201, the terminal device determines rate matching information in a time unit based on the downlink control information.

In the embodiment of the present invention, the rate matching information is used for the terminal device to receive data.

In specific implementation, the UE first detects the first search space, and detects a Physical Downlink Control CHannel (PDCCH) to obtain DCI; the DCI is used for carrying the rate matching information; optionally, the DCI is DCI format1-0 or the DCI is DCI format 1-1.

Wherein the first search space is a UE-specific search space; accordingly, the DCI is UE-specific DCI. Optionally, the time unit is a time unit in which a data channel scheduled in a downlink is located; the time unit may be 1 slot, or may have other values.

In some embodiments, the rate matching information is location information of the SSB.

Optionally, the location information of the SSB may be whether to send the SSB at the candidate sending location in the time unit; taking a scheduled time unit as one slot as an example, since the sending position of the SSB in one slot is predefined, a bitmap of 2bits information is carried through the DCI, and is used to indicate whether the SSB is sent at the sending position in one slot. If the sending positions of 2 SSBs are predefined in one slot, whether the SSBs are sent at the corresponding positions is judged according to the bit values of the sending positions of the 2 SSBs in the bitmap. For example, the bit values corresponding to the transmission positions of 2 SSBs are 10, a bit value of 1 indicates that the corresponding position transmits an SSB, and a bit value of 0 indicates that the corresponding position does not transmit an SSB.

Optionally, the location information of the SSB may also be a transmission condition of the SSB in the time unit. Since the sending position of the SSB in one slot is predefined, taking the example that the actually transmitted SSB always occupies the candidate sending position of the continuous SSB, the sending condition of the SSB in the time unit includes:

not sending SSBs at the candidate send position within the time cell, sending all SSBs at the candidate send position within the time cell, and sending only the first SSB at the candidate send position within the time cell.

Optionally, the location information of the SSB is: the last transmission location of the SSB within the time cell. Since the SSBs are transmitted at successive candidate locations, when the last transmission location of the SSB within the time cell is determined, the candidate transmission location before the last transmission location also transmits the SSB.

Based on the above embodiments, the UE determines the location information of the SSB in the time unit according to the indication of the DCI, that is, determines the rate matching information in the time unit.

In other embodiments, the UE cannot determine the rate matching information in the time unit only according to DCI, and needs to determine the rate matching information in combination with a bitmap of the actual transmission positions of SSBs. In specific implementation, the UE acquires a bitmap of an actual sending position of the SSB from the network equipment through a system message; the UE can determine whether to transmit the SSB at the candidate transmission position of the SSB in the time cell by using one transmission position index of the SSB indicated in the DCI and the received bitmap. Here, the one transmission position of the SSB indicated in the DCI may be the actual transmission position of the last SSB or may be the actual transmission position of any one SSB.

For example, an 8-bit bitmap is used to characterize the actual transmission position of the SSB, the value of the bitmap is 01000100, and when the transmission position of the last SSB indicated by the DCI corresponds to the 6 th bit value in the 8-bit bitmap, the UE may determine the position corresponding to the 2 nd bit value in the 8-bit bitmap to transmit the SSB. When the transmission position of the first SSB indicated by the DCI corresponds to the 6 th bit value in the 8-bit bitmap, the UE may determine that no SSB is transmitted in other positions in the 8-bit bitmap.

In the embodiment of the present invention, when the network device schedules Downlink transmission of the UE, the location information of the SSB in a time unit in which the UE transmits a Physical Downlink Shared Channel (PDSCH) is notified through DCI. After receiving the location information of the SSB, the UE performs rate matching on Resource Elements (REs) overlapping with resources of the scheduled PDSCH at the indicated location of the SSB when receiving the PDSCH, so as to correctly receive the PDSCH. As shown in fig. 6, the slots where the SSB indices 2 and 3 are located are the same as the slots where the PDSCH is located, and the DCI indicates the location information of the SSB in the PDSCH scheduling resource, that is, whether the SSB indices 2 and 3 are actually transmitted in the slots; when the SSB index2, 3 is transmitted in the slot, when the UE receives the PDSCH, the REs overlapping with the resources of the scheduled PDSCH at the indicated SSB position are rate-matched to correctly receive the PDSCH.

As shown in fig. 7, the optional processing flow of the method for transmitting control information applied to a network device according to the embodiment of the present invention includes the following steps:

step S301, the network device sends DCI to the UE, where the DCI is used for the UE to determine rate matching information used for data reception by the UE in a time unit.

In some embodiments, the rate matching information is location information of the SSB

The descriptions of the DCI and the SSB location information in the embodiment of the present invention are the same as those in step S201, and are not repeated here

An embodiment of the present invention further provides a terminal device, as shown in fig. 8, a schematic diagram of a composition structure of the terminal device 400 includes:

a processing unit 401 configured to determine rate matching information in a time unit based on the DCI; and the rate matching information is used for the terminal equipment to receive data.

In some embodiments, the processing unit is configured to detect a first search space to obtain the DCI, where the DCI is used to carry the rate matching information. Wherein the rate matching information is location information of the SSB.

In some embodiments, the location information of the SSB is: whether SSB is sent at the candidate sending position in the time unit; or, the location information of the SSB is: a transmission status of the SSB within the time cell; or, the location information of the SSB is: the last transmission position of the SSB in the time cell.

Wherein the sending condition of the SSB in the time unit includes: not sending SSBs at the candidate send position within the time cell, sending all SSBs at the candidate send position within the time cell, and sending only the first SSB at the candidate send position within the time cell.

An application scenario of the embodiment of the present invention is as follows: the SSBs are sent on consecutive candidate locations.

In some embodiments, the processing unit 401 is configured to obtain a bitmap of actual sending positions of SSBs from a network device; and determining whether to transmit the SSB at the candidate transmission position of the SSB in the time unit based on the bitmap and one transmission position index of the SSB indicated in the DCI.

And the DCI is located in a first search space of the terminal equipment and is used for carrying the rate matching information. The rate matching information is the location information of the SSB.

In some embodiments, the sending unit 501 is further configured to send a bitmap of actual sending positions of SSBs to the terminal device; and the bitmap and one transmission position index of the SSB indicated in the DCI are used by the terminal device to determine whether to transmit the SSB at the candidate transmission position of the SSB in the time unit.
