Description

Method and device for sending and receiving access information and transmission system

Technical Field

The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a transmission system for transmitting and receiving access information.

Background

In order to meet the increasing demand for wireless data services from the deployment of the 4 th generation communication system 4G, efforts have been made to develop an improved 5 th generation communication system 5G. The 5G communication system is also called a "4G network" or a "Long Term Evolution (LTE) system".

5G communication systems are known to be implemented in higher frequency bands (e.g., above 3 GHz) in order to achieve higher data rates. The high-frequency communication is characterized by relatively serious path loss and penetration loss and close relation with the atmosphere in space transmission. Because the wavelength of the high-frequency signal is extremely short, a large number of small-sized antenna arrays can be applied, so that the beam forming technology can obtain more accurate beam directions, the coverage capability of the high-frequency signal is improved by the advantages of the narrow beam technology, the transmission loss is compensated, and the method is a great characteristic of high-frequency communication.

In a communication system using beamforming techniques, transmit beamforming and/or receive beamforming is used. Transmit beamforming is generally a technique that focuses the signal transmitted by each antenna in a particular direction using multiple antennas. 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 signals is increased due to the use of transmit beamforming and the interference to other users is significantly reduced because almost no signals are received in other directions than the relevant direction. Receive beamforming is a technique in which reception of radio waves is focused in a specific direction by using a receive antenna array in a receiver. The signal sensitivity of the signal entering in the correlation direction is increased by using the reception beamforming, but the signal entering in a direction other than the correlation direction is removed from the reception signal, thereby blocking the interference signal.

In order to support transmission of various system bandwidths, users access through a minimum system bandwidth (i.e., 6 physical resource blocks around a central frequency point) around a central frequency, that is, user common information is sent to the users through a system broadcast channel and a synchronization signal in the minimum system bandwidth, and the users receive the system broadcast channel and the synchronization signal only from the minimum system bandwidth. However, in the 5G communication system, the user common information needs to be repeatedly sent to the user through different beams in a beam scanning manner, and the 5G communication system is required to support more flexible network side device/user bandwidth configuration, for example, the network side device can support multiple system bandwidth configurations, and can support access of users with various bandwidths under any system bandwidth configuration, so that if the 5G communication system still adopts the minimum system bandwidth access manner of the conventional LTE, the problem of too large access delay is faced. The problem is more prominent as the frequency resources used by the communication system are higher, the beams are narrower, and the number of beams is larger. No effective solution has been proposed to the related problems.

One or more second sub-bands including sub-band 1, sub-band 2, and sub-band 3 (of course, a scene including only sub-band 1 is also true) are respectively distributed on both sides of the first sub-band. When the first sub-band is located at the very middle of the transmission frequency band, the one or more second sub-bands are center-symmetrical with respect to the first sub-band located at the center position.

Note that the transmission band is a band for a transmitting end (network side device in this embodiment) of the access information. In other words, the transmission bandwidth refers to a frequency domain resource corresponding to a maximum bandwidth supported by the transmitting end or a maximum bandwidth supported by the transmitting end, which allows data service transmission, as a transmission band here. The first sub-band is part or all of a transmission band. For example, for a base station, a transmission frequency band is a frequency domain resource corresponding to a maximum downlink bandwidth supported by the base station.

Optionally, any one of the i +1 th designated orders is a cyclic shift order of another designated order. For example, the second specified order when i =1 is: the third designated order for sub-block 1, sub-block 2, sub-block 3, sub-block 4, when i =2, is: sub-block 2, sub-block 3, sub-block 4, sub-block 1. Of course, the number of steps of the cyclic shift may be determined according to the number of blocks of the access information actually transmitted, i.e. for example, when i =5, the sixth specified order is: the seventh designated order for sub-block 1, sub-block 2, sub-block 3, sub-block 4, sub-block 5, when i =6, may also be: sub-block 3, sub-block 4, sub-block 5, sub-block 1, sub-block 2.

Further preferably, the scanning of the beam is understood herein as a Reference Signal Received Power (RSRP) measurement of the beam.

Optionally, when the access information includes a downlink control channel for carrying uplink grant information in an access process, the downlink control channel is only sent on a minimum bandwidth by default.

Optionally, the access information on the first sub-band is further used for indicating at least one of: the bandwidth capability of the user side equipment, the system bandwidth capability corresponding to the sending frequency band, and the sending information of the sub information block in the second sub band.

Specifically, when the access information includes a random access channel or an uplink beam reference signal, the access information carries user bandwidth capability. It is noted that the user bandwidth capability includes the maximum access bandwidth or the maximum transmission bandwidth that the user can support.

Optionally, the information transmitted by the sub-information block in the second sub-band includes: whether the second sub-band transmits the access information; a sub-information block index transmitted by the access information on the second subband; a sub-information block order transmitted on the second sub-band of the access information; a designated period value transmitted by the access information on the second subband.

It should be noted that, when the indication information is carried in the access information transmission of the first sub-band, the network side device may carry the indication information in an explicit manner or an implicit manner through the access information of the first sub-band. Explicit means are for example: indicating by the content in the sub information block of the access information in the first sub-band, implicitly for example: the sub information blocks of the access information are carried by different transmission time-frequency resource positions, different transmission sequences and the like in the first sub-band. It should be noted that, when the ue is notified through the higher layer signaling, the indication information can be notified to the ue only by the base station or the network after the ue accesses the system. It is not excluded in the embodiments of the present invention that one or more of the above indication information is carried by access information on the first sub-band, and the other one or more is signaled by a higher layer signaling.

Optionally, the meaning of the N sub information blocks carrying the access information is that the network side device performs block processing on the access information, and sets the multiple sub blocks after the block processing in the sub information blocks respectively. It is noted that N is a positive integer.

Note that the above-mentioned designated transmission order is the transmission order of the sub-blocks of the access information. The designated sequence is preset by the network side equipment and the user side equipment.

Optionally, the N sub-information blocks of the access information each have an independent decoding capability, and the receiving end can be instructed to decode each received sub-information block. It should be noted that the plurality of information blocks are a plurality of components of the access information, where an intersection of the plurality of components is empty, and the intersection includes the access information. And dividing the access information into a plurality of information blocks after uniform coding, wherein any one of the information blocks contains the access information.

Optionally, the N sub information blocks are sent cyclically according to a preset period configured in advance by the network side device and the user side device.

Specifically, the designated period is a period corresponding to a transmission opportunity for transmitting the access information in the designated transmission order. The network side device may select to send or not send the access information in a specified period according to actual needs, but the corresponding user side device needs to monitor and/or receive the access information in the specified period.

Optionally, the specified period corresponding to the first subband is equal to the specified period corresponding to any one subband in the P second subbands.

And the specified period corresponding to the first sub-band is in a multiple relation with the specified period corresponding to any one sub-band in the P second sub-bands.

Through the steps, the problem of overlarge access time caused by the adoption of the minimum system bandwidth transmission access in the related technology is solved, and the effect of reducing the average access time delay of the users in the 5G communication system is achieved.

Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention or portions thereof contributing to the prior art may be embodied in the form of a software product, where the computer software product is stored in a storage medium (such as a ROM/RAM, a magnetic disk, and an optical disk), and includes several instructions for enabling a terminal device (which may be a mobile phone, a computer, a server, or a network-side device, etc.) to execute the methods according to the embodiments of the present invention.

Optionally, a bandwidth of the first sub-band is a minimum bandwidth in the receiving frequency band. Generally, the minimum bandwidth is pre-agreed by the network side device and the user side device.

Specifically, when the specified sub-band includes a first sub-band and a second sub-band, step 402 further includes, based on the step of including the first sub-band: and receiving one or more sub information blocks in the N sub information blocks sent by the network side equipment on the M second subbands.

It should be noted that, since the bandwidth capability of the ue is generally not stronger than that of the network device, M is a positive integer less than or equal to P.

Note that the reception band is a band for a transmission end (network side device in this embodiment) of the access information. In other words, the receiving bandwidth refers to a maximum bandwidth supported by the receiving end or a frequency domain resource corresponding to the maximum bandwidth supported by the receiving end, where the maximum bandwidth allows data service transmission, is a receiving frequency band here. The first sub-band is part or all of the reception frequency band.

Specifically, in this embodiment, the following scenario is also provided to understand the technical solutions described in the above embodiments.

Scene 1

The different bandwidths have the same period, the network side equipment is a base station, and the user side equipment is UE.

A base station notifies some system information, common information, uplink random access information, and the like to a UE through a Physical Broadcast Channel (PBCH), and the UE needs to receive and acquire information indicated in the PBCH during initial access.

It is assumed that one PBCH includes four sub-blocks (alternatively referred to as information blocks), PBCH sub-block 0, PBCH sub-block 1, PBCH sub-block 2, PBCH sub-block 3, respectively, wherein the broadcast information indicated in the four sub-blocks may be the same or different. As shown in fig. 1, the base station transmits PBCH sub-block 0, PBCH sub-block 1, PBCH sub-block 2, and PBCH sub-block 3 at time t0, time t0+ k, time t0+2k, and time t0+3k, respectively, over the minimum bandwidth (UE 1 bandwidth), and it should be noted that the blocks labeled with the same pattern (color) at a specific time in fig. 1 are a sub-band, for example, there are four sub-bands in total under the system bandwidth in fig. 1, where the base station transmits PBCH only on three sub-bands near the middle position of the system bandwidth as needed. And respectively sending the PBCH sub-block 1, the PBCH sub-block 2, the PBCH sub-block 3 and the PBCH sub-block 0 at the time t0, the time t0+ k, the time t0+2k and the time t0+3k on a sub-band which is closest to the minimum bandwidth outside the minimum bandwidth, and respectively sending the PBCH sub-block 2, the PBCH sub-block 3, the PBCH sub-block 1 and the PBCH sub-block 1 at the time t0, the time t0+ k, the time t0+2k and the time t0+3k on a sub-band which is next to the minimum bandwidth outside the minimum bandwidth.

Fig. 5 is a distribution diagram of the division and location of a sub-tape according to an embodiment of the present invention. As shown in fig. 5, the minimum bandwidth is located in the middle of the system bandwidth, or the center frequency of the minimum bandwidth and the center frequency of the system bandwidth coincide or differ by no more than 12 subcarrier intervals. The minimum bandwidth includes 3 sub-bands, each of which 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-band 2, and sub-band 3 in fig. 5.

The division of the sub-bands in the system bandwidth is determined according to different UE bandwidths supported by the system, for example, fig. 5 shows that the minimum bandwidth is one UE bandwidth supported by the system, the minimum bandwidth and sub-band 1 are combined to form another UE bandwidth supported by the system, the minimum bandwidth, sub-band 1 and sub-band 2 are combined to form a third UE bandwidth supported by the system, and the minimum bandwidth, sub-band 1, sub-band 2 and sub-band 3 are combined to form a fourth UE bandwidth supported by the system, which is also called the system bandwidth.

By the sub-band division mode and the resource mapping and sending mode of PBCH in each sub-band, users supporting different bandwidths can acquire different sub-blocks of PBCH from corresponding bandwidths, so that users supporting wider bandwidths can acquire system broadcast information more quickly. For example, for UE3, it can receive PBCH on the minimum bandwidth, subband 1 and subband 2, so it can obtain complete information of four sub-blocks of PBCH after receiving PBCH at time t0+ k, so the access delay of UE3 is k; for UE2, it can receive the PBCH on subband 1 and the minimum bandwidth, so it can obtain the complete information of four sub-blocks of PBCH after receiving the PBCH at time t0+2k, and therefore the access delay of UE2 is 2k; for UE1, its bandwidth is the smallest, it can only receive PBCH on the smallest bandwidth, so it needs to obtain complete information of four sub-blocks of PBCH after receiving PBCH at time t0+3k, 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 PBCH, but may also be a Beam Reference Signal (BRS), a Synchronization Signal (SS), an uplink Physical Random Access Channel (PRACH), a downlink control Channel, a downlink data Channel, an uplink control Channel, or an uplink data Channel, or any combination thereof.

In addition, it should be noted that each subband is not limited to only transmitting PBCH, and scanning transmission of beams may also be performed for multiplexing PBCH and other signals or channels, where the other signals or channels include: one or more of a Beam Reference Signal (BRS), a Synchronization Signal (SS), a paging Signal, and the like. Wherein PBCH and other signals or channels can be multiplexed in one sub-band in a frequency, time, or time division manner. And there may not be a multiplexing of other signals or channels on all PBCH transmission time instants, PBCH transmission subbands. Fig. 6 is a distribution diagram of the division and position of another seed tape according to the invention. As shown in fig. 6, the synchronization signal and the PBCH are time division multiplexed in one subband and are multiplexed only on the minimum bandwidth and only at time t0+ k and time t0+2k, i.e., the SS is transmitted only on the minimum bandwidth, and the transmission period of the SS may be different from that of the PBCH.

Scene 2

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

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

Fig. 7 is a distribution diagram of division and location of still another sub-tape according to an embodiment of the present invention. As shown in fig. 7, PBCH on different subbands has different transmission periods, where the transmission period of PBCH on the minimum bandwidth is k/2, the transmission period of PBCH on subband 1 is k, and the transmission period of PBCH on subband 2 is 2k. And sequentially and circularly transmitting the four sub-blocks of the PBCH on the minimum bandwidth in a PBCH transmission period according to the sequence of the PBCH sub-block 0, the PBCH sub-block 1, the PBCH sub-block 2 and the PBCH sub-block 3. It is noted that it is also possible to transmit only a part of the four sub-blocks of PBCH on sub-bands other than the minimum bandwidth, for example, in fig. 7, PBCH sub-block 1 and PBCH sub-block 3 are cyclically transmitted on sub-band 1, and PBCH sub-block 2 is cyclically transmitted on sub-band.

Different UEs perform blind detection according to a PBCH sending period with a minimum bandwidth or a minimum PBCH sending period, where the PBCH sending period with the minimum bandwidth or the minimum PBCH sending period is predetermined by the base station and the UEs, and the UEs with different bandwidth capabilities perform blind detection on an actual bandwidth according to an actual bandwidth capability, for example, in fig. 4, UE1 defaults to perform blind detection on the PBCH on the minimum bandwidth, UE2 defaults to perform blind detection on the PBCH on the minimum bandwidth and subband 1, and UE3 defaults to perform blind detection on the minimum bandwidth, subband 1, and subband 2.

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

Before the UE accesses, the UE carries out blind detection according to a PBCH sending period with the minimum bandwidth or the minimum PBCH sending period, wherein the PBCH sending period with the minimum bandwidth or the minimum PBCH sending period is preset by a base station and the UE, and the UE with different bandwidth capabilities carries out blind detection on the actual bandwidth according to the actual bandwidth capabilities. After the UE is accessed, the base station informs the PBCH sending periods of different sub-bands under the bandwidth capability corresponding to the UE through a high-level signaling special for the user, so that after the UE is accessed, the UE monitors and receives the PBCH on the different sub-bands according to the actual sending period of the base station.

By the PBCH sending and receiving mode, the access delay of the UE with smaller bandwidth capability is reduced, the expense of the PBCH is effectively controlled, and the difference between the access delay of the UE with different bandwidth capabilities and the average access delay is effectively smoothed. As shown in FIG. 7, the access delay of UE1 is 3k/2, and the access delay of UE2 and UE3 is k. Compared with the scheme (different sub-bands have the same PBCH sending period) in the embodiment 1 of the invention, the access delay of the UE3 is unchanged, and the access delays of the UE2 and the UE1 are obviously reduced.
