Technical field

The present invention relates to the field of communications technologies, and relates to a method and device for transmitting and receiving access information, a transmission system and a storage medium.

Background technique

In order to meet the increased demand for wireless data services since the deployment of the 4th generation communication system (4G), efforts have been made to develop an improved 5th generation communication system (5G). The 5G communication system is also referred to as a "post 4G network" or a "long term evolution (LTE) system".

A 5G communication system is considered to be implemented in a higher frequency band (eg, above 3 GHz, and for example, at 6 Ghz to 100 Ghz) in order to achieve higher data rates. The characteristics of high-frequency communication are that it has relatively serious path loss and penetration loss, and its spatial transmission is closely related to the atmosphere. Due to the extremely short wavelength of the high-frequency signal, a large number of small antenna arrays can be applied, so that the beamforming technology can obtain a more accurate beam direction, and the advantages of the narrow beam technology can improve the coverage of the high-frequency signal and compensate for the transmission loss. A major feature of communication.

In a communication system using beamforming techniques, transmit beamforming and/or receive beamforming is used. Transmit beamforming is generally a technique that uses multiple antennas to concentrate the signals transmitted by each antenna in a particular direction. The combination of the plurality of antennas is referred to as an array antenna, and each antenna included in the array antenna is referred to as an antenna element. The propagation of the signal is increased by the use of transmit beamforming, and since no signal is received in other directions than the relevant direction, Therefore, the interference to other users is significantly reduced. Receive beamforming is a technique in which the reception of radio waves is concentrated in a specific direction by using a receiving antenna array in a receiver. The signal sensitivity of the incoming signal in the relevant direction is increased by the use of receive beamforming, but the incoming signal is removed from the received signal in a direction other than the relevant direction, thereby preventing the interfering signal.

However, with the introduction of the antenna array and the beam, it is found that the user side device has a problem of large access delay.

Summary of the invention

detailed description

The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted, The embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

It is to be understood that the terms "first", "second" and the like in the specification and claims of the present invention are used to distinguish similar objects, and are not necessarily used to describe a particular order or order.

In a Long Term Evolution (LTE) system, all user equipments can support various system bandwidths. To support the transmission of various system bandwidths, the user equipment passes the minimum system bandwidth around the center frequency (ie, 6 physical resources around the center frequency). Block access, that is, the user equipment shared information is sent to the user equipment in the minimum system bandwidth through the system broadcast channel and the synchronization signal, and the user equipment only receives the system broadcast channel and the synchronization signal from the minimum system bandwidth.

However, in the 5G communication system, the shared information of the user equipment needs to be repeatedly transmitted to the user equipment through different beams by means of beam scanning, and the 5G communication system is required to support a more flexible network side device/user bandwidth configuration, for example, the network side device can support A variety of system bandwidth configurations that support access to user devices of various bandwidths in any system bandwidth configuration. Therefore, if the LTE minimum system bandwidth access mode is adopted in the 5G communication system, the access delay will be too large. And as the frequency resources used by the communication system are higher, the beam is narrower, and the number of beams is larger, the problem is more prominent. Therefore, in the embodiment of the present invention, a method for transmitting access information and a receiving method are provided. The sending device (for example, a base station) can send access information on a designated sub-band, thus allowing the base station to send on multiple sub-bands. Access information, in which case the receiving device (for example, the UE) may receive the access information on multiple sub-bands without waiting for the access information sent by the single sub-band, which is equivalent to increasing the bandwidth for transmitting the access information. Therefore, the delay of receiving the access information by the UE is reduced, thereby improving the acquisition speed of the access information, thereby reducing the access delay.

Optionally, in the embodiment, the following scenarios are also provided to understand the technical solutions described in the foregoing embodiments.

scene 1

The network side device may include: a base station, and the user side device may include various user equipments UE such as a mobile phone and an Internet of Things device.

The base station notifies the UE of some system information, public information, uplink random access information, and the like through a physical broadcast channel (PBCH). The UE needs to receive and know the information indicated in the PBCH during initial access.

Suppose a PBCH includes four sub-blocks (or information blocks), which are PBCH sub-block 0, PBCH sub-block 1, PBCH sub-block 2, and PBCH sub-block 3. The broadcast information indicated in the four sub-blocks may be the same. It may also be different. As shown in FIG. 1, the base station transmits PBCH sub-block 0, PBCH sub-block 1, PBCH sub-block 2, and at time t0, t0+k, t0+2k, and t0+3k, respectively, on the minimum bandwidth (UE1 bandwidth). PBCH sub-block 3, it is worth noting that the block labeled as the same pattern (color) for a particular moment in FIG. 5 is a sub-band. For example, there are four sub-bands under the system bandwidth in FIG. 1, wherein the base station only needs to The PBCH is transmitted on three sub-bands near the middle of the system bandwidth. On the subband closest to the minimum bandwidth outside the minimum bandwidth, PBCH subblock 1, PBCH subblock 2, PBCH subblock 3 and respectively are transmitted at time t0, time t0+k, time t0+2k, time t0+3k, respectively. The PBCH sub-block 0 transmits the PBCH sub-block 2 and the PBCH sub-block 3 at the t0 time, the t0+k time, the t0+2k time, and the t0+3k time, respectively, on the sub-band that is next to the minimum bandwidth outside the minimum bandwidth. PBCH sub-block 1 and PBCH sub-block 1.

FIG. 5 is a distribution diagram of division and position of a sub-band according to an embodiment of the present invention. As shown in Figure 5, the minimum bandwidth is in the middle of the system bandwidth, or the center frequency of the minimum bandwidth and The center frequencies of the system bandwidths coincide or the difference between the two does not exceed 12 subcarrier spacing. In addition to the minimum bandwidth, there are three sub-bands, wherein each sub-band is composed of two discontinuous frequency bands, one of which is located above the minimum bandwidth and the other of which is located below the minimum bandwidth, such as sub-band 1, sub-picture in FIG. Belt 2 and sub-band 3. In some cases, the two frequency bands of each sub-band are symmetrically centered on the minimum bandwidth and distributed on both sides of the minimum bandwidth. The minimum bandwidth may be one of the foregoing first sub-bands. The sub-band 1, the sub-band 2, and the sub-band 3 may be one of the aforementioned second sub-bands.

The division of subbands in the system bandwidth is determined according to different UE bandwidths supported by the system. For example, the minimum bandwidth of FIG. 5 is a UE bandwidth supported by the system, and the minimum bandwidth and subband 1 are combined to be another UE bandwidth supported by the system. The minimum bandwidth, subband 1 and subband 2 are combined to be the third UE bandwidth supported by the system, and the minimum bandwidth, subband 1, subband 2 and subband 3 are combined to support the fourth medium UE bandwidth supported by the system, that is, the system bandwidth. .

Through the sub-band division mode and the resource mapping and transmission mode of the PBCH in each sub-band, users supporting different bandwidths can obtain different sub-blocks of the PBCH from the corresponding bandwidth, so that users with wider bandwidth can obtain system broadcasts faster. information. For example, for UE3, it can receive the minimum bandwidth, PBCH on subband 1 and subband 2, so it can obtain the complete information of the four subblocks of PBCH after receiving the PBCH at time t0+k, so UE3 The access delay is k; for UE2, it can receive the minimum bandwidth and the PBCH on subband 1, so that it can obtain the complete information of the four sub-blocks of the PBCH after receiving the PBCH at time t0+2k, so UE2 The access delay is 2k; for UE1, its bandwidth is the smallest, it can only receive the PBCH on the minimum bandwidth, so it needs to obtain the four sub-blocks of the PBCH after receiving the PBCH at time t0+3k. Complete information, so the access delay of UE1 is 3k, and its access delay is the longest.

It should be noted that the access information in the embodiment of the present invention is not limited to only the PBCH, and may also be a Beam Reference Signal (BRS), a synchronization signal. (Synchronization Signal, SS for short), Physical Random Access Channel (PRACH), downlink control channel, downlink data channel, uplink control channel, or uplink data channel, or any between them. combination.

In addition, it should be noted that each subband is not limited to only transmitting PBCH, and may also be used for PBCH and other signals or channels multiplexed together for beam scanning transmission, where other signals or channels include: beam reference signal (Beam) One or more of Reference Signal (BRS), Synchronization Signal (SS), and paging signal. The PBCH and other signals or channels may be multiplexed in one subband in a frequency division, time division, or time division manner. And it may not be that at the time of all PBCH transmissions, there are other signals or channels multiplexed on the PBCH transmission subband. Figure 6 is a distribution diagram of the division and position of another seed strip in accordance with the present invention. As shown in FIG. 6, the synchronization signal and the PBCH are time-division multiplexed in one sub-band, and are multiplexed only on the minimum bandwidth and only at the time t0+k and t0+2k, that is, the SS is only at the minimum. The bandwidth is transmitted, and the transmission period of the SS may be different from the transmission period of the PBCH.

Scene 2

Different bandwidths have different periods. The network side device is a base station, and the user side device is a UE.

Access information (e.g., PBCH) on different subbands may have different transmission periods. In this way, different PBCH transmission periods can be configured for UEs with different bandwidths. For example, the base station will configure a smaller PBCH transmission period for UEs with smaller bandwidth capabilities, so that this type of UE can access the system more quickly. For a UE with a large bandwidth capability, a larger PBCH transmission period may be appropriately configured instead of always configuring the same PBCH transmission period with a UE having a smaller bandwidth capability to avoid excessive PBCH overhead.

7 is a distribution diagram of division and position of still another sub-band according to an embodiment of the present invention. As shown in FIG. 7, the PBCHs on different subbands have different transmission periods, the PBCH transmission period on the minimum bandwidth is k/2, the transmission period of the PBCH on the subband 1 is k, and the PBCH on the subband 2 is transmitted. The delivery period is 2k. The four sub-blocks of the PBCH are cyclically transmitted on the PBCH transmission cycle in the order of PBCH sub-block 0, PBCH sub-block 1, PBCH sub-block 2, and PBCH sub-block 3 in the minimum bandwidth. It should be noted that only sub-blocks of the four sub-blocks of the PBCH may be transmitted on the sub-bands other than the minimum bandwidth. For example, in FIG. 7, only the PBCH sub-block 1 and the PBCH sub-block 3 are cyclically transmitted on the sub-band 1. The PBCH sub-block 2 is only cyclically transmitted on the sub-band.

Different UEs perform blind detection according to the minimum bandwidth PBCH transmission period or the minimum PBCH transmission period, where the minimum bandwidth PBCH transmission period or the minimum PBCH transmission period is pre-agreed by the base station and the UE, and the UEs with different bandwidth capabilities follow the actual The bandwidth capability is blindly detected on the actual bandwidth. For example, in Figure 4, UE1 blindly detects the PBCH by default on the minimum bandwidth. UE2 blindly detects the PBCH by default on the minimum bandwidth and subband 1, and UE3 defaults to the smallest and widest, subband 1 and subband 2 The PBCH is detected blindly.

It should be noted that the base station indicates to the UE whether there is PBCH transmission on other subbands outside the minimum bandwidth at the current transmission moment through the PBCH on the minimum bandwidth, and if indicated, the UE receives on the subband indicated with the PBCH. PBCH, otherwise, the UE will not blindly detect or receive the PBCH on the indicated subband.

Before the UE accesses, the UE performs blind detection according to the minimum bandwidth PBCH transmission period or the minimum PBCH transmission period, where the minimum bandwidth PBCH transmission period or the minimum PBCH transmission period is pre-agreed by the base station and the UE, and has different bandwidths. The capable UE is blindly detected on the actual bandwidth according to the actual bandwidth capability. After the UE accesses, the base station notifies the UE of the PBCH transmission period of different sub-bands in the bandwidth capability corresponding to the UE by the user-specific high-layer signaling, so after the UE accesses, the UE performs the actual sub-band according to the base station. The transmission cycle monitors and receives the PBCH.

The above-mentioned PBCH transmission and reception mode reduces the access delay of the UE with smaller bandwidth capability, and effectively controls the PBCH overhead, the access delay of the UE with different bandwidth capabilities, and the average access delay. The difference between them is effectively smoothed. As shown in Figure 7, the connection of UE1 The incoming delay is 3k/2, and the access delay of UE2 and UE3 is k. Compared with the solution in the first embodiment of the present invention (the different sub-bands have the same PBCH transmission period), the access delay of the UE3 is unchanged, and the access delays of the UE2 and the UE1 are significantly reduced.
