Description

System information transmission method, communication device and related equipment Technical Field

The present application relates to the field of communications technologies, and in particular, to a system information transmission method, a communications device, and related devices.

Background

For the high frequency band, the transmission of signals is based on beamforming. Beamforming is a technique that limits the energy of a transmitted signal to a certain beam direction to increase the signal transmission efficiency. To achieve full coverage, the network device performs beam scanning, and the New Radio (NR) protocol specifies that synchronization signal/physical broadcast channel blocks (synchronization signal and physical broadcast channel block, SS/PBCH blocks) repeatedly occur in a period, and some types of physical downlink control channels (physical downlink control channel, PDCCH) (e.g., type 0-PDCCH) are transmitted with the same beam as the corresponding SS/PBCH blocks. In some scenarios, the Type0-PDCCH is time-division arranged, with different beams occupying different time slots. However, the persistent Type0-PDCCH signaling may result in the failure to transmit other signals for a longer period of time. In the future where the number of beams supported by the network device is increasing, how to balance the transmission of Type0-PDCCH signals and other signals is a problem to be solved.

Disclosure of Invention

The application provides a transmission method, a communication device and related equipment of system information, which can provide transmission of Type0PDCCH for each wave beam of network equipment and ensure transmission of other signals, thereby improving communication efficiency.

In a first aspect, the present application provides a system information transmission method, which may be executed by a network device, and specifically includes: the network equipment sends at least two first signals to the terminal equipment based on a first period, wherein one first signal corresponds to one wave beam of the network equipment; the first period comprises a first time slot and a second time slot, the first time slot is used for transmitting the first signal, the second time slot is used for transmitting other signals except the first signal, and at least one second time slot is located between two first time slots.

In a second aspect, the present application provides another system information transmission method, which may be executed by a terminal device, and specifically includes that the terminal device monitors first signals based on a first period, where one of the first signals corresponds to one beam of one network device; the first period comprises a first time slot and a second time slot, the first time slot is used for transmitting the first signal, the second time slot is used for transmitting other signals except the first signal, and at least one second time slot is positioned between two first time slots; and the terminal equipment receives the first signal according to the monitoring result.

In one possible design, the first signal is a Type0-PDCCH signal, and the other signals are uplink signals or downlink signals except for the Type0-PDCCH signal, where the uplink signals refer to uplink signals of other terminal devices except for the terminal device that receives the Type0-PDCCH signal, and the downlink signals may be downlink signals sent to the terminal device that receives the Type0-PDCCH signal, or downlink signals sent to other terminal devices except for the terminal device that receives the Type0-PDCCH signal.

In a high-frequency scene, for example, a frequency band of 52.6GHz and above, in order to ensure the coverage performance of a cell, certain requirements are required for the number of beams and Type0-PDCCH signals corresponding to the beams, the design of the period comprising the first time slot and the second time slot is adopted, and on the premise of ensuring the coverage performance of the cell, the transmission of the Type0-PDCCH signals can be supported, and the condition that other signals cannot be transmitted for a long time, such as uplink signals of other terminal equipment in the cell, can be avoided, so that the communication performance is improved.

In one possible design, to achieve a more flexible configuration, the first slots in the first period are divided into at least two first slot groups, one first slot group comprising at least two first slots, and at least one second slot being located between the at least two first slot groups.

It can be understood that, when the uplink and downlink time slot ratios in the first period are different, the configuration of g first time slot groups is the same, or the configuration of g second time slot groups is the same. Therefore, aiming at different uplink and downlink time slot ratios, the distribution of the first time slot and the second time slot is not required to be designed respectively, the signaling overhead is saved, and the communication efficiency is improved.

To facilitate an understanding of the relevant aspects of embodiments of the present application, some concepts related to the embodiments of the present application are illustratively described.

Quasi co-location relationship: quasi co-located (QCL) relationships, the association in the present application may also be referred to as mapping, correspondence, correlation. When there is a QCL between the two signals, at least one of the same delay spread, the same doppler spread, the same average gain, the same average delay, the same spatial parameters and the same beam may be used to transmit or receive the signals. The parameters of quasi co-location include: at least one of doppler spread, doppler shift, average delay, delay spread and spatial domain receive parameters. QCL relationships can be divided into four classes: 'QCL-TypeA': doppler shift, doppler spread, average delay, delay spread }; 'QCL-TypeB': doppler shift, doppler spread; 'QCL-TypeC': doppler shift, average delay }; 'QCL-TypeD': spatial reception parameters }. When the QCL relation parameters are selected, they can be selected arbitrarily, for example, the average gain and 'QCL-type' are selected.

Beam: the beam may be embodied in the NR protocol as a spatial filter (spatial domain filter), or spatial filter, or spatial parameter (spatial parameter). The beam used to transmit the signal may be referred to as a transmit beam (transmission beam, tx beam), may be referred to as a spatial transmit filter (spatial domain transmission filter) or spatial transmit parameters (spatial transmission parameter); the beam used to receive the signal may be referred to as a receive beam (Rx beam), may be referred to as a spatial receive filter (spatial domain receive filter) or spatial receive parameters (spatial RX parameter).

The transmit beam may refer to a distribution of signal strengths formed in spatially different directions after signals are transmitted through the antennas, and the receive beam may refer to a distribution of signal strengths of wireless signals received from the antennas in spatially different directions.

Furthermore, the beam may be a wide beam, or a narrow beam, or other type of beam. The technique of forming the beam may be a beamforming technique or other technique. The beamforming technique may specifically be a digital beamforming technique, an analog beamforming technique, or a hybrid digital/analog beamforming technique, etc.

The beam generally corresponds to a resource or a signal, for example, when the network device measures the beam, the network device measures different beams through different resources, the terminal device feeds back the measured quality of the resource, and the network device knows the quality of the corresponding beam. In data transmission, beam information is also indicated by its corresponding resource. For example, the network device indicates information of the terminal device physical downlink shared channel (physical downlink shared channel, PDSCH) beam by means of resources in the transmission configuration indication (transmission configuration indicator, TCI) of the downlink control information (downlink control information, DCI).

Alternatively, a plurality of beams having the same or similar communication characteristics are regarded as one beam. One or more antenna ports may be included in a beam for transmitting data channels, control channels, and sounding signals, etc. One or more antenna ports forming a beam may also be considered as a set of antenna ports.

In the embodiment of the present application, if no specific description is made, the beam refers to a transmission beam of the network device. In beam measurement, each beam of the network device corresponds to a resource, and thus the beam to which the resource corresponds can be uniquely identified by an index of the resource.

The beams may be represented in the standard using QCL relationships.

System information block: the system information blocks (system information block, SIB) are included, and a plurality of system information blocks are included in one cell, and the system information blocks bear different information, for example, SIB1, mainly bear configuration information of some cells, for example, information related to random access, information related to a physical downlink control channel (physical downlink control channel, PDCCH), information related to other information blocks, information of a UE accessing the cell, information of an identification of the cell and the like.

Synchronization signal block: the synchronization signal block (Synchronization Signal block, SSB) may also be referred to as SS (Synchronization Signal )/PBCH (Physical broadcast channel, physical broadcast channel) block, where the SS/PBCH block includes at least one of a primary synchronization signal (Primary Synchronization signal, PSS), a secondary synchronization signal (Secondary Synchronization signal, SSs), a physical broadcast channel (Physical broadcast channel, PBCH), and a demodulation reference signal (Demodulationed Reference Signal, DMRS). The SS/PBCH block may also be referred to as SSB/PBCH block, and the signals in the SS/PBCH block or SSB/PBCH block may be the same antenna ports.

Referring to fig. 2, a signaling interaction flow of a terminal device accessing a cell is illustrated. The terminal device blindly detects the SSB, and after blindly detecting the SSB, receives the master information block (main information block, MIB) information carried in the SSB, where the MIB signal includes configuration information of the SIB1 control resource set (control resource set, CORESET) and the common search space (CSS, common search space), and other indications, such as a subcarrier spacing. The terminal device receives the CORESET of SIB1 according to the indication, where the CORESET of SIB1 contains the PDCCH of SIB 1. Illustratively, the PDCCH of SIB1 may also be referred to as a "Type0-PDCCH", the PDCCH signal of SIB1 is referred to as a "Type0-PDCCH signal", it is understood that the "Type0-PDCCH signal" is not intended to limit the signal itself, and other designations are possible in other embodiments. The PDCCH of SIB1 indicates relevant information such as PDSCH position of SIB1 and modulation coding strategy. The terminal device receives the PDSCH according to the indication of the PDCCH. In NR, PDCCH of SIB1 and physical downlink shared channel (physical downlink shared channel, PDSCH) of SIB1 have the same subcarrier spacing. Wherein SIB1 specific information is transmitted in PDSCH, and PDCCH of SIB1 indicates time-frequency resource location of PDSCH and other related information of the PDSCH, such as modulation coding information. For the frequency band above 52.6GHz, the information is transmitted based on beamforming, so the PDCCH and PDSCH transmissions of SIB1 are also based on beamforming. Since the signal received first by the terminal device is SSB, and the SSB of the base station corresponds to each beam, the beam of SSB can be regarded as a reference standard, and the relevant information of SIB1 is also associated with the beam of SSB, that is, the beam of SIB1 is the same as the beam of SSB, and the two information are transmitted by using the same beam.

The method for transmitting system information and related devices according to the embodiments of the present application are described below with reference to the accompanying drawings, where based on a transmission period with a special design, a network device sends Type0-PDCCH to a terminal device through multiple beams. Referring to fig. 4, fig. 4 is a flowchart illustrating a method for transmitting control information according to an embodiment of the present application. As shown in fig. 4, the transmission method of the system information includes the steps of:

101: the network device determines at least one first period for transmitting a first signal, one first signal corresponding to one beam of the network device. In other words, the first period is a transmission period of the first signal. In a first period, a plurality of beams of the network equipment respectively send corresponding first signals;

it will be appreciated that 101 is an optional step, the network device may determine the at least one first period according to system parameters or according to a protocol.

102: the network device sends a first signal to the terminal device based on the first period, wherein the first period comprises a first time slot and a second time slot, the first time slot is used for transmitting the first signal, the second time slot is used for transmitting other signals except the first signal, and at least one second time slot is positioned between two first time slots;

The first signal may be a Type0-PDCCH signal, for example. This first time slot, used to transmit the Type0-PDCCH signal, may be referred to as a "Type0-PDCCH time slot". The second time slot is used to transmit other signals, which may be uplink signals or downlink signals, except for the Type 0-PDCCH. One of the first time slots is used for one beam of the network device to transmit its Type0-PDCCH signal, that is, one beam of the network device transmits its Type0-PDCCH signal in one of the first time slots. Accordingly, the terminal equipment receives the Type0-PDCCH signal based on the first time slot. And a second time slot is used for transmitting other signals, and the terminal equipment transmits the uplink signals in the second time slot by taking the second time slot as an uplink signal as an example, and correspondingly, the network equipment receives the uplink signals from the terminal equipment in the second time slot.

Alternatively, the network device may send the configuration of the first period to the terminal device, for example: if there are multiple possible configuration manners in the first period, the network device may send the configured index, for example, an index (index) in table 5 or table 8 below, to the terminal device; alternatively, the network device may send the configuration itself of the first period to the terminal device.

103: the terminal device communicates with the network device based on the first period. Specifically, the terminal device monitors a first signal and receives the first signal;

according to the first period, the terminal equipment monitors the first signal on the corresponding time domain resource, after the monitoring is successful, the terminal equipment receives the Type0-PDCCH signal from the network equipment on the time domain resource corresponding to the first time slot, and the terminal equipment can send the signal to the network equipment or the terminal equipment can receive other signals except the Type0-PDCCH signal from the network equipment on the time domain resource corresponding to the second time slot.

By adopting the transmission method of the system information, at least one time slot for transmitting other signals is designed among a plurality of time slots for transmitting the Type0-PDCCH signals, and particularly under the condition that more wave beams are required to be transmitted by network equipment in a scene of more than 52.6GHz, the other signals can be ensured to be transmitted in time, and the performance of a communication system is improved.

In the following, the beams of the network device are further described, and the beams of the network device have indexes (index), which may be represented by indexes of Synchronization Signal Blocks (SSBs), that is, the indexes of the beams of the network device may be the same as indexes of the SSBs corresponding thereto. The beam of the network device may be divided into a plurality of beam packets, one beam packet including greater than or equal to 1 beam. The Type0-PDCCH signal of the beam corresponding to the network device may be divided into a plurality of Type0-PDCCH packets, one Type0-PDCCH packet including the Type0-PDCCH signal corresponding to one beam packet, i.e., one beam packet including N beams, and the corresponding one Type0-PDCCH packet may include N Type0-PDCCH signals. The beam packet and the Type0-PDCCH packet are equivalent in terms of technical essence.

The number of Type0-PDCCH signals transmitted by the network device is related to the number of beams supported by the network device, and the number of beams may be different according to different scenarios, alternatively, the number of beams may be greater than 4, for example, may be 32, 64 or 128, and then the network device transmits 32, 64 or 128 Type0-PDCCH signals accordingly.

Next, the above-described first period is exemplarily described.

The first period is a transmission period of the Type0-PDCCH signal. In a first period, multiple beams of the network device respectively transmit Type0-PDCCH signals, one beam corresponds to one Type0-PDCCH, in other words, the network device transmits one Type0-PDCCH signal through one beam. Therefore, in one transmission period, the transmission of the Type0-PDCCH of a plurality of beams of the network device can be completed. It can be appreciated that if there are multiple first periods, multiple beams of the network device may repeatedly transmit Type0-PDCCH signals in different first periods. Optionally, in some embodiments, based on the number of beams, the network device may transmit a Type0-PDCCH signal based on a plurality of first periods, which may be included in one or more second periods.

The first period may include one or more time units, and in different embodiments, the number of time units included in the second period may be different. Illustratively, the time units may be time slots, and the number of time slots included in one first period may be different depending on different system parameter configurations. Illustratively, the first period may be one radio frame, which may include 40 slots. The second period may include 2 first periods, i.e., two radio frames, and 1 second period includes 80 slots.

A first period includes at least one first time slot and at least one second time slot. One first period may correspond to one Type0-PDCCH packet, and a Type0-PDCCH signal in the one Type0-PDCCH packet is transmitted in at least one first slot in the corresponding first period, and at least one first slot in the first period for transmitting the Type0-PDCCH signal may be referred to as a "Type0-PDCCH slot packet". In some embodiments, a Type0-PDCCH signal may be transmitted in a first time slot, that is, a Type0-PDCCH signal may be transmitted in a first time slot by one beam; in other embodiments, multiple Tpye0-PDCCH signals may be transmitted within one first time slot, in other words, multiple beams may transmit Type0-PDCCH signals within one first time slot.

Under different system parameters (numerology), the first period may take different configurations, more examples of which are given below.

Referring to fig. 4, a first periodic structure is illustrated from a symbol level. As shown, 1 first period includes 10 slots, i.e., t=10, where slots 0 to 7 are designed as first slots for transmitting Type0-PDCCH signals and slots 8 and 9 are designed as second slots for transmitting other signals. Taking 1 Type0-PDCCH signal transmitted in 1 slot as an example, the initial symbol of the Type0-PDCCH signal is symbol 0, the Type0-PDCCH signal occupies 3 symbols 0-2, and the other signals occupy 11 symbols 3-13. In one example, the other signal may be a PDSCH signal carrying SIB 1. In fig. 4, 1 slot corresponds to Type0-PDCCH signals of 1 beam, and 8 beams of the network device may be supported to transmit corresponding Type0-PDCCH signals in a first period. If the network device has 64 beams, it takes 8 first periods to transmit.

In other embodiments, the second period and the first period are configured accordingly based on the number of beams supported by the network device. For example, as shown in fig. 5, 2 Type0-PDCCH signaling opportunities may be designed in 1 slot, and then the first period may support 16 beams to transmit corresponding Type0-PDCCH signals. If the network device has 128 beams, it takes 8 first periods to transmit. Alternatively, the 8 first periods may be included in the 2 second periods.

In a high-frequency scene, for example, a frequency band of 52.6GHz and above, in order to ensure the coverage performance of a cell, certain requirements are required for the number of beams and Type0-PDCCH signals corresponding to the beams, the design of the period comprising the first time slot and the second time slot is adopted, and on the premise of ensuring the coverage performance of the cell, the transmission of the Type0-PDCCH signals can be supported, and the condition that other signals cannot be transmitted for a long time, such as uplink signals of other terminal equipment in the cell, can be avoided, so that the communication performance is improved.

The first period is further described below. A first period may include T slots, T.gtoreq.2. In different embodiments, the value of T may be different, in other words, the number of slots included in one first period may be different. K second time slots and N first time slots are included in the T time slots, and K is more than or equal to 1. The relationship of T, K and N satisfies: n=t-K. It should be noted that, the configuration parameters of the first period may be predefined by the protocol, or the configuration parameters of the first period may be dynamically configured by signaling, for example, carried in a physical broadcast channel (physical broadcast channel, PBCH). In various embodiments, the configuration parameter of the first period may be at least two of T, K, or N. For example, the configuration parameters of the first period may be T and K, the configuration parameters of the first period may be T and N, or the configuration parameters of the first period may be K or N. Illustratively, the value of T may be any one of the sets {4,5,6,8, 10, 12, 16, 20, 32, 36, 40 }.

In some embodiments, in one first period, a plurality of first time slot groups may be included, different first time slot groups may include different numbers of first time slots, and one or more second time slots are filled between different first time slot groups.
