Detailed Description

So that the manner in which the features and techniques of the embodiments of the present application can be understood in more detail, a more particular description of the application, briefly summarized below, may be had by reference to the appended drawings, which are not intended to be limiting of the embodiments of the present application.

Before describing embodiments of the present application in detail, the relevant contents of the NR system will be briefly described.

Common channels and signals in NR systems, such as synchronization signals (Synchronization Signal) and broadcast channels, need to cover the entire cell by means of multi-beam scanning in order for UEs within the cell to be able to receive. The multi-beam transmission of SS is achieved by defining SS/physical broadcast channel (Physical Broadcast Channel, PBCH) set (burst set). One 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 the same number of synchronization signals for the same number of beams as SS/PBCH blocks within the cell. The maximum number of SS/PBCH blocks L is related to the frequency band of the system: when the frequency of the system is 3GHz at maximum, the value of L is 4; when the frequency range of the system is 3GHz to 6GHz, the value of L is 8; the value of L is 64 when the frequency of the system is in the range of 6GHz to 52.6 GHz.

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

All SS/PBCH blocks in 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 the parameter SSB-timing of a high layer and comprises 5ms,10ms,20ms,40ms,80ms,160ms and the like.

A schematic diagram of SSB distribution in different subcarriers is shown in fig. 2; fig. 2 shows the slot distribution of SS/PBCH blocks under different subcarrier checkpoints and frequency bands, taking a 15kHz subcarrier spacing, l=4 as an example, one slot (slot) contains 14 symbols (symbols) and can carry two SS/PBCH blocks. 4 SS/PBCH blocks are distributed in the first two slots in the 5ms time window. Where L is the maximum number of SSBs, the number of SSBs actually transmitted may be smaller than L. The network device informs the UE of the position of the actually transmitted SSB through system information in the form of bitmap.

Transmission of SSBs over unlicensed spectrum is briefly described below.

Unlicensed spectrum is a nationally and regionally divided spectrum that can be used for radio communications and is generally considered to be a shared spectrum, i.e., communication devices in different communication systems can use the spectrum 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 individual communication systems using unlicensed spectrum for wireless communication to co-exist friendly over the spectrum, some countries or regions have stipulated regulatory requirements that must be met using unlicensed spectrum. For example, in the european region, the communication device follows the principle of Listen-Before-Talk (LBT), i.e. the communication device needs to perform channel interception Before performing signal transmission on a channel of the unlicensed spectrum, and only when the channel interception result is that the channel is idle, the communication device can perform signal transmission; if the channel listening result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device is unable to signal. And in order to ensure fairness, in one transmission, the communication device cannot use the unlicensed spectrum channel for signal transmission for a period exceeding the maximum channel occupation time (Maximum Channel Occupation Time, MCOT).

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

Also, since LBT over unlicensed spectrum has the potential to fail, SSB transmissions may not be transmitted in a predefined pattern (pattern); one improvement is to introduce multiple candidate locations within a time window for possible SSB transmissions. For example, in the frequency band below 6GHz, there are at most 8 SSB indexes, the network device may notify the UE of a specific SSB transmission position by using an 8-bit bitmap 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 timing of obtaining the usage right of the channel is not determined, 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 which of the plurality of candidate locations the SSB actually transmits the SSB at, for rate matching when the UE receives the downlink transmission data.

In view of the uncertainty of obtaining the channel usage rights on the unlicensed spectrum, the number Y of candidate locations of SSBs configured by the network device is greater than the number X of SSBs actually transmitted by the network device within one transmission window. That is, for each demodulation reference signal (Demodulation Reference Signal, DRS) transmission window, the network device may determine to transmit SSBs using X candidate positions available from among the Y candidate positions according to the detection result of LBT within the DRS transmission window, and the positions of the X SSBs actually transmitted within different DRS transmission windows may be different. Therefore, consideration needs to be given to how to indicate the location of the SSB actually transmitted within one DRS window. In the NR transmission technology on unlicensed spectrum below 6GHz, an improvement is that the maximum number of SSB transmissions is 8, and there are a maximum number of y=64 candidate transmission positions within a time window.

Optionally, the communication system 100 may further include a network controller, a mobility management entity, and other network entities, which are not limited by the embodiment of the present application.

It should be understood that a device having a communication function in a network/system according to an embodiment of the present application may be referred to as a communication device. Taking the communication system 100 shown in fig. 4 as an example, the communication device may include the network device 110 and the terminal device 120 with communication functions, where the network device 110 and the terminal device 120 may be the specific devices described above, which are not described herein again; the communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in this embodiment of the present application.

The optional processing flow of the transmission method of the control information applied to the terminal device provided by the embodiment of the application, as shown in fig. 5, comprises the following steps:

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

In the embodiment of the application, the rate matching information is used for the terminal equipment to receive data.

In specific implementation, the UE first detects a first search space, detects a physical downlink control CHannel (Physical Downlink Control chnnel, PDCCH) and obtains DCI; the DCI is used for bearing the rate matching information; optionally, the DCI is DCI format1-0 or the DCI is DCI format1-1.

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 downlink scheduled data channel is located; the time unit may be 1 slot, or may be another value.

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

Alternatively, the location information of the SSB may be whether or not to transmit the SSB at the candidate transmission location in the time unit; taking a scheduled time unit as an example of a slot, because the transmission position of the SSB in the slot is predefined, the bitmap carrying 2bits of information through the DCI is used for indicating whether to transmit the SSB in the transmission position in the slot. If the transmission positions of 2 SSBs are predefined in a slot, determining whether to transmit SSBs in the corresponding positions by using the bit values of the transmission positions corresponding to the 2 SSBs in the bitmap. For example, the bit values corresponding to the transmission positions of 2 SSBs are 10, respectively, and the bit value 1 indicates that the corresponding position transmits the SSB, and the bit value 0 indicates that the corresponding position does not transmit the SSB.

Alternatively, the location information of the SSB may be a transmission case of the SSB in the time unit. Since the transmission positions of SSBs in one slot are predefined, taking as an example that the actually transmitted SSBs always occupy the candidate transmission positions of consecutive SSBs, the transmission cases of the SSBs in the time unit include:

the SSB is not transmitted at the candidate transmission position in the time unit, all SSBs are transmitted at the candidate transmission position in the time unit, and only the first SSB is transmitted at the candidate transmission position in the time unit.

Optionally, the location information of the SSB is: the last transmission position of SSB in the time unit. Since SSBs are transmitted at consecutive candidate positions, when the last transmission position of an SSB within the time unit is determined, the candidate transmission position preceding the last transmission position also transmits the SSB.

Based on the above embodiment, 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 is only able to determine the rate matching information in the time unit based on the DCI, and needs to determine in combination with the bitmap of the actual transmission location of the SSB. In the specific implementation, the UE acquires the bitmap of the 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 unit through one transmission position index of the SSB indicated in the DCI and the received bitmap. Here, one transmission position of the SSB indicated in the DCI may be an actual transmission position of the last SSB or an 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 bitmap value 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 can determine that the SSB is transmitted at the position corresponding to the 2 nd bit value in the 8-bit bitmap. 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 the SSB is not transmitted at other positions in the 8-bit bitmap.

In the embodiment of the application, when the network equipment schedules downlink transmission of the UE, the UE is informed of the position information of the SSB in a time unit where the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) transmission is located through DCI. After receiving the SSB location information, the UE performs rate matching on Resource Elements (REs) overlapping with the scheduled PDSCH resources at the indicated SSB location when receiving the PDSCH so as to correctly receive the PDSCH. As shown in fig. 6, slots where SSB indexes 2 and 3 are located are the same as slots where PDSCH is located, and DCI indicates location information of SSB in the PDSCH scheduling resource, that is, whether SSB indexes 2 and 3 in the slots are actually transmitted; when SSB index2, 3 is transmitted in the slot, the ue performs rate matching with REs overlapping with the resources of the scheduled PDSCH at the indicated SSB position when receiving the PDSCH, so as to correctly receive the PDSCH.

The optional processing flow of the transmission method of control information applied to network equipment provided by the embodiment of the application, as shown in fig. 7, includes the following steps:

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

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

The description of the location information of DCI and SSB in the embodiment of the present application is the same as that in step S201, and is not repeated here

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 the position information of the SSB.

In some embodiments, the location information of the SSB is: whether SSB is transmitted at the candidate transmission position in the time unit; alternatively, the location information of the SSB is: the transmission condition of the SSB in the time unit; alternatively, the location information of the SSB is: and the last sending position of the SSB in the time unit.

Wherein, the sending situation of the SSB in the time unit includes: the SSB is not transmitted at the candidate transmission position in the time unit, all SSBs are transmitted at the candidate transmission position in the time unit, and only the first SSB is transmitted at the candidate transmission position in the time unit.

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

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