Description

The present invention relates to the field of wireless communication technology, in particular to signal transmission devices, systems and methods.

High-frequency technology has begun to be used in wireless communication for signal transmission, and path loss increases due to high-frequency characteristics. To reduce path loss, a viable method is to use large massive multiple-input multiple-output (large-scale MIMO for short) to form very high antenna gain and path. To compensate for the loss.

In prior art, large-scale MIMO has a large number (hundreds) of antennas. High antenna gains are formed, but the beams formed using large-scale MIMO technology have a very narrow width. Therefore, one beam cannot cover all users in the cell.
However, in the prior art, the antenna needs to cover all users in the cell for information such as broadcast channels and common channels. The beam formed by large-scale MIMO cannot cover all users in the cell. Therefore, some users in the cell cannot receive messages such as broadcast messages, which reduces the stability of communication.

According to the signal transmission device, system and method according to the present invention, the first network device detects the first signal transmitted by the second network device in the first resource group. The first resource group contains N resources, where N is a positive integer greater than 1, and each resource in the first resource group corresponds to one first signal. Then, the first network device determines the mth resource in the second resource group according to the nth resource in the first resource group and the first correspondence. The second resource group contains M resources, M is a positive integer greater than 1, and the mth resource in the second resource group is of at least two candidate resources in the second resource group. One of them, the nth resource in the first resource group has a first correspondence with each of at least two candidate resources in the second resource group, and the range of m is 0 <. m ≦ M, and the range of n is 0 <n ≦ N. Therefore, in high frequency scenarios, full cell coverage of the signal (such as sync signals, system messages, or broadcast messages) is guaranteed. That is, the UE interacts with the second network device (access device) by performing the discovery within the first resource group. Since the first resource group contains multiple resources, it is possible to perform transmissions to different UEs on each resource of one resource group. That is, different UEs have different resources for detecting signals. That is, the UE can determine the communication that meets the requirement from the correspondence of a plurality of different resources, and according to the nth resource in the first resource group, the mth resource in the second resource group. To determine. Therefore, the UE does not need to acquire the second signal transmitted by the second network device by blind detection of multiple candidate second resources in the second resource group, or the second resource. Signals are sent over multiple resources in the group, thereby improving system efficiency and performance.

In contrast, in the prior art, the beam is relatively narrow in high frequency scenarios and cannot cover the entire cell. Therefore, the resources that the base station exchanges with the UE for synchronization channels, measurement pilot signals, broadcast channels, etc. are always the same for all UEs within the coverage of the base station. That is, all UEs in the entire cell detect synchronization channels, measurement pilot signals, broadcast channels, etc. on the same resource. However, when using large-scale MIMO technology, the beam formed is so narrow that it cannot meet the requirement to cover the UE in the entire cell using the same resources.

And describe it completely. Obviously, the embodiments described are some, but not all, of the embodiments of the present invention. All other embodiments obtained by one of ordinary skill in the art based on embodiments of the invention without creative effort shall fall within the scope of protection of the invention.

FIG. 1 is a schematic diagram of an access and interaction process between a user device and a base station according to an embodiment of the present invention. With reference to Figure 1, the process involves the following steps:

Step 1: The base station transmits a synchronization channel to user equipment (UE for short).

Step 2: The base station sends the measurement pilot signal to the UE.

Step 3: The base station sends a broadcast channel to the UE.

Step 4: The base station sends a system message to the UE.

Step 5: The base station receives the random access channel transmitted by the UE.

Step 6: The base station sends a random access response channel to the UE.

Step 7: The base station receives the Radio Resource Control (RRC) request message transmitted by the UE.

Step 8: The base station sends an RRC request confirmation message to the UE.

Step 9: The base station transmits the downlink data channel to the UE, or the base station receives the uplink data channel transmitted by the UE.

Specifically, in the prior art, the beam is relatively narrow in high frequency scenarios and cannot cover the entire cell. Therefore, the resources that the base station exchanges with the UE for synchronization channels, measurement pilot signals, broadcast channels, etc. are always the same for all UEs within the coverage of the base station. That is, all UEs in the entire cell detect synchronization channels, measurement pilot signals, broadcast channels, etc. on the same resource. However, when using large-scale MIMO technology, the beam formed is so narrow that it cannot meet the requirement to cover the UE in the entire cell using the same resources.

To solve the problems described above, embodiments of the present invention provide signal transmission devices, systems such that UE coverage across cells with the channels and messages described above is performed when large-scale MIMO technology is used. And provide a method.

Hereinafter, the signal transmission device, system, and method according to the embodiment of the present invention will be described with reference to specific embodiments.

FIG. 2 is a schematic configuration diagram of a network device according to an embodiment of the present invention. The network device corresponds to the following first network device. The network device may be a user device UE. Specifically, the UE may be a smartphone, a tablet computer, an in-vehicle communication device, or the like. Referring to FIG. 2, the network apparatus includes a detection module 100 and a decision module 101.

The detection module 100 is configured to detect the first signal transmitted by the second network device in the first resource group, the first resource group contains N resources, and N is greater than or equal to 1. A large positive integer, each resource in the first resource group corresponds to one first signal,
The decision module 101 is configured to determine the nth resource in the first resource group and the mth resource in the second resource group according to the first correspondence, and the second resource group is M. Containing resources, M is a positive integer greater than 1, and the mth resource in the second resource group is one of at least two candidate resources in the second resource group.

The range of is 0 <n ≤ N.

According to the network device provided in this embodiment of the present invention, the detection module detects the first signal transmitted by the second network device in the first resource group.

Therefore, in high frequency scenarios, full cell coverage of the signal (such as sync signals, system messages, or broadcast messages) is guaranteed. That is, the UE interacts with the second network device (access device) by performing the discovery within the first resource group. Since the first resource group contains multiple resources, it is possible to perform transmissions to different UEs on each resource of one resource group.

Therefore, the resources that the base station exchanges with the UE for synchronization channels, measurement pilot signals, broadcast channels, etc. are always the same for all UEs within the coverage of the base station. That is, all UEs in the entire cell detect synchronization channels, measurement pilot signals, broadcast channels, etc. on the same resource.

The network device may be an access network device. Specifically, the access network device may be a base station, an evolved NodeB, a relay device, or the like. Referring to FIG. 4, the network device includes a transmission module 200.

The transmit module 200 is configured to transmit the first signal in the first resource group, where the first resource group contains N resources, where N is a positive integer greater than 1 and the first. Each resource in the resource group corresponds to one first signal, and the nth resource in the first resource group has a first correspondence with the mth resource in the second resource group. , The second resource group contains M resources, M is a positive integer greater than 1, and the mth resource in the second resource group is at least two candidates in the second resource group.

According to the network apparatus provided in this embodiment of the present invention, the transmitting module transmits the first signal in the first resource group. The first resource group contains N resources, where N is a positive integer greater than 1, and each resource in the first resource group corresponds to one first signal.

Therefore, in high frequency scenarios, full cell coverage of the signal (such as sync signals, system messages, or broadcast messages) is guaranteed. That is, the second network device (access device) transmits the first signal to the UE in the first resource group. Since the first resource group contains multiple resources, it is possible to perform transmissions to different UEs on each resource of one resource group.

That is, the UE can determine the communication that meets the requirement from the correspondence of a plurality of different resources, and according to the nth resource in the first resource group, the mth resource in the second resource group.

Therefore, the UE does not need to acquire the second signal transmitted by the second network device by blind detection of multiple candidate second resources in the second resource group, or the second resource. Signals are sent over multiple resources in the group, thereby improving system efficiency and performance.

In contrast, in the prior art, the beam is relatively narrow in high frequency scenarios and cannot cover the entire cell. Therefore, the resources that the base station exchanges with the UE for synchronization channels, measurement pilot signals, broadcast channels, etc. are always the same for all UEs within the coverage of the base station. That is, all UEs in the entire cell detect synchronization channels, measurement pilot signals, broadcast channels, etc. on the same resource.

FIG. 7 is a schematic flowchart of a signal transmission method according to an embodiment of the present invention. This method is executed by the first network device, and the first network device is a user device UE, and specifically, a smartphone, a tablet computer, an in-vehicle communication device, or the like may be used. With reference to Figure 7, this method involves the following steps:

Step 100: The first network device detects the first signal transmitted by the second network device in the first resource group, the first resource group contains N resources, and N is 1. A larger positive integer, each resource in the first resource group corresponds to one first signal.

Step 101: The first network device determines the mth resource in the second resource group according to the nth resource in the first resource group and the first correspondence.

The second resource group contains M resources, M is a positive integer greater than 1, and the mth resource in the second resource group is of at least two candidate resources in the second resource group. One of them, the nth resource in the first resource group has a first correspondence with each of at least two candidate resources in the second resource group, and the range of m is 0 <. m ≦ M, and the range of n is 0 <n ≦ N.

According to the signal transmission method provided in the embodiment of the present invention, the first network device detects the first signal transmitted by the second network device in the first resource group. The first resource group contains N resources, where N is a positive integer greater than 1, and each resource in the first resource group corresponds to one first signal. Then, the first network device determines the mth resource in the second resource group according to the nth resource in the first resource group and the first correspondence. The second resource group contains M resources, M is a positive integer greater than 1, and the mth resource in the second resource group is of at least two candidate resources in the second resource group. One of them, the nth resource in the first resource group has a first correspondence with each of at least two candidate resources in the second resource group, and the range of m is 0 <. m ≦ M, and the range of n is 0 <n ≦ N. Therefore, in high frequency scenarios, full cell coverage of the signal (such as sync signals, system messages, or broadcast messages) is guaranteed. That is, the UE interacts with the second network device (access device) by performing the discovery within the first resource group. Since the first resource group contains multiple resources, it is possible to perform transmissions to different UEs on each resource of one resource group. That is, different UEs have different resources for detecting signals. That is, the UE can determine the communication that meets the requirement from the correspondence of a plurality of different resources, and according to the nth resource in the first resource group, the mth resource in the second resource group. To determine. Therefore, the UE does not need to acquire the second signal transmitted by the second network device by blind detection of multiple candidate second resources in the second resource group, or the second resource. Signals are sent over multiple resources in the group, thereby improving system efficiency and performance.

In contrast, in the prior art, the beam is relatively narrow in high frequency scenarios and cannot cover the entire cell. Therefore, the resources that the base station exchanges with the UE for synchronization channels, measurement pilot signals, broadcast channels, etc. are always the same for all UEs within the coverage of the base station. That is, all UEs in the entire cell detect synchronization channels, measurement pilot signals, broadcast channels, etc. on the same resource. However, when using large-scale MIMO technology, the beam formed is so narrow that it cannot meet the requirement to cover the UE in the entire cell using the same resources.

If necessary, the first resource group is used as an example. Different resources within the first resource group are time-division and can have the same cycle. For example, the cycle of the first resource in the first resource group is t0, t0 + T, t0 + 2T ,. .. .. The cycle of the second resource in the first resource group is t1, t1 + T, t1 + 2T ,. .. .. Where t0 and t1 are hourly indexes, time units are symbols, time slots or subframes, and T is a cycle. Furthermore, the following resource groups may have similar attributes and are not described in detail here.

In the aforementioned embodiment, the N resources in the first resource group are any type of resource: time domain resource, frequency domain resource, code resource, space resource, or power resource.

Specifically, in the case of a time domain resource, the first signal may be used as an example, and the second network device may transmit the first signal on a plurality of time domain resources. A plurality of time domain resources form the first resource group described above, and each time domain resource can have a correspondence with one or more resources of the second resource group.

Frequency domain resources are similar to time domain resources and have different physical resource blocks PRBs or subbands.

The sequence resource includes any one of a signal transmission sequence, a spreading code used by the signal, a scrambling code used by the signal, or a mask added during the cyclic redundancy code CRC process.

Further, when the resource group is a sequence resource and the sequence identifier of the resource in the resource group is ID1, the sequence identifier has a correspondence relationship with the resource in the next resource group correspondingly. For example, the following resource group is a time domain resource. Then, the sequence identifier corresponds to the resource t1 in the next resource group. For example, if the next resource group is a frequency domain resource, the sequence identifier corresponds to resource f1 in the next resource group. For example, if the next resource group is a time-frequency resource, the sequence identifier corresponds to the resources (t1, f1) in the next resource group.

Similarly, for example, if the sequence identifier is ID2, the corresponding time-frequency resource is (t2, f2).

The synchronization channel includes a primary synchronization signal PSS and a secondary synchronization signal SSS. PSS can be generated using the following formulas and tables. Suppose one sector supports twelve beams and one base station is divided into three sectors. PSS needs to support 3 x 12 = 36 beams, which requires 36 code resources. For example, NIDs 10 to 35 in the table represent a total of 36 code resources.

For space resources, in high frequency scenarios, a single beam has a relatively narrow width and a second network device (access network device) sends the beam in different directions to perform full cell coverage. There is a need. Therefore, beams in different directions represent space resources.

Due to the power resources, the access network device or UE can perform signal transmission by using different powers, and the UE can use different powers to perform demodulation. Demodulation pilot data power and power information is required during data demodulation. Therefore, the process of transmitting different beams can have different power information.

The M resources in the second resource group are any one type of resource: time domain resource, frequency domain resource, code resource, space resource, or power resource.
The Q resources in the third resource group are any type of resource: time domain resource, frequency domain resource, code resource, space resource, or power resource.

FIG. 9 is a schematic diagram of a space resource according to an embodiment of the present invention. With reference to FIG. 9, a relatively wide range of beams can include specific subbeams. For example, the synchronization channel uses a wide beam B0 containing four subbeams with relatively narrow beam widths: B00, B01, B02, and B03. When UE1 detects a synchronization channel on B00, it can be seen that the second network device transmits the synchronization channel on each resource of the second resource group (B00, B01, B02, B03). UE1 discovers the synchronization channel on B00, i.e., it discovers the synchronization channel on the mth resource in the second resource group. The identifier of B00 may have a correspondence relationship with the resource of the next second signal, and the correspondence relationship may be one-to-one correspondence or one-to-many correspondence. That is, UE1 detects B00 for the mth resource in the second resource group, and recognizes that the identifier of B00 has a correspondence relationship with the qth resource in the third resource group. UE1 then performs the following operation on the qth resource in the third resource group. Certainly, as described above, the above-mentioned correspondence may be a one-to-many correspondence. That is, the identifier of B00 corresponds to a plurality of resources in the third resource group. In this case, the UE is preferably in a third resource group and can select resources that meet the requirements of the UE to perform the following operations:

The second network device will be described below. FIG. 10 is a schematic flowchart of another signal transmission method according to the embodiment of the present invention. This method is performed by a second network device, which may specifically be a base station, eNB, access network device, hotspot device, relay device, or the like. With reference to FIG. 10, this method involves the following steps:

Step 200: The second network device sends the first signal in the first resource group, the first resource group contains N resources, N is a positive integer greater than 1, and the second Each resource in one resource group corresponds to one first signal.

The nth resource in the first resource group has a first correspondence with the m resource in the second resource group, the second resource group contains M resources, and M is 1. A greater positive integer, the mth resource in the second resource group is one of at least two candidate resources in the second resource group, and the nth resource in the first resource group. Has a first correspondence with each of at least two candidate resources in the second resource group, the range of m is 0 <m ≤ M, and the range of n is 0 <n ≤ N. is there.

According to the signal transmission method provided in the embodiment of the present invention, the second network apparatus transmits the first signal in the first resource group. The first resource group contains N resources, where N is a positive integer greater than 1, and each resource in the first resource group corresponds to one first signal. The nth resource in the first resource group has a first correspondence with the m resource in the second resource group, the second resource group contains M resources, and M is 1. A greater positive integer, the mth resource in the second resource group is one of at least two candidate resources in the second resource group, and the nth resource in the first resource group.

Therefore, in high frequency scenarios, full cell coverage of the signal (such as sync signals, system messages, or broadcast messages) is guaranteed. That is, the second network device (access device) transmits the first signal to the UE in the first resource group. Since the first resource group contains multiple resources, it is possible to perform transmissions to different UEs on each resource of one resource group. That is, different UEs have different resources for detecting signals. That is, the UE can determine the communication that meets the requirement from the correspondence of a plurality of different resources, and according to the nth resource in the first resource group, the mth resource in the second resource group. To determine. Therefore, the UE does not need to acquire the second signal transmitted by the second network device by blind detection of multiple candidate second resources in the second resource group, or the second resource. Signals are sent over multiple resources in the group, thereby improving system efficiency and performance.

In contrast, in the prior art, the beam is relatively narrow in high frequency scenarios and cannot cover the entire cell. Therefore, the resources that the base station exchanges with the UE for synchronization channels, measurement pilot signals, broadcast channels, etc. are always the same for all UEs within the coverage of the base station. That is, all UEs in the entire cell detect synchronization channels, measurement pilot signals, broadcast channels, etc. on the same resource. However, when using large-scale MIMO technology, the beam formed is so narrow that it cannot meet the requirement to cover the UE in the entire cell using the same resources.

The solution of the embodiment of the present invention will be described with reference to the interaction between the first network device and the second network device.

FIG. 12 is a schematic diagram of an interaction process of the signal transmission method according to the embodiment of the present invention. For example, the first network device is the UE and the second network device is the base station. With reference to FIG. 12, this method involves the following steps:

Step 1: The base station uses different beams to transmit synchronization channels, broadcast channels, system messages, paging messages, measurement pilot signals, and random access response channels at different time units.

Specifically, FIG. 13 is a schematic view of step 1 of FIG. 12 according to the embodiment of the present invention. Referring to FIG. 13, the time unit is the time domain resource described above. Assuming that the time unit is a subframe, the base station uses beam 1 to use beam 1 in the first time unit (subframe 0) for the first sync channel, the first broadcast channel, and the first system message. The base station uses beam 2 to send a second sync channel, a second broadcast channel, and a second system message in the second time unit (subframe 2), by analogy. The base station uses the nth beam to transmit the nth synchronization channel, the nth broadcast channel, and the nth system message to the nth time unit (subframe 2n).

Optionally, the first sync channel and the second sync channel can use different sequences. For example, the first sync channel uses sequence S1 and the second sync channel uses sequence S2. That is, the first synchronization channel can use a different code or sequence resource than that used by the synchronization channel on another time domain resource.

The first time unit may be a wireless frame, a time slot, a symbol, or the like.

Step 2: The base station uses different beams, the first measurement signal, the second measurement signal ,. .. .. And the nth measurement signal is transmitted.

Specifically, FIG. 14 is a schematic view of step 2 of FIG. 12 according to the embodiment of the present invention. Referring to FIG. 14, the nth measurement signal sequence, time-frequency position, pattern, power information, etc. correspond to the nth synchronization channel sequence in step 1. Correspondence may be related to the location of the time frequency resource of the nth synchronization channel or the sequence of the nth synchronization channel. Further, as the nth measurement signal, the same beam as the nth synchronization signal can be used.

Step 3: The UE performs frequency and time synchronization with the base station transmitting the nth synchronization channel by detecting the nth synchronization channel.

Specifically, the detection process may be of slip correlation. Further, the base station transmits synchronization channels on a plurality of first resources, for example, n synchronization channels on n first resources. The UE can obtain information (sequence, time-frequency position, pattern and power information) of the nth measurement signal by detecting the nth synchronization channel. Further, the information of the nth measurement signal is used to instruct the UE to detect the nth measurement signal on the nth second resource. In addition, the UE detects the nth measurement signal on the nth second resource and uses the Reference Signal Receiving Power (RSRP for short) and the Received Signal Strength Indication (Received Signal Strength Indication) for short. RSSI) and other information of the nth measurement signal are measured to perform cell selection.

Further, the cell selection performed by the UE is described as follows, for example, the sequences corresponding to the N synchronization channels corresponding to cell 1 are the first time unit, the second time unit, and the second, respectively. Time unit of n ,. .. .. , And the Nth time unit, S11, S12, S1n and S1N.

For example, UE1 finds the nth synchronization channel of cell 1 by search and determines information such as the pattern and power of the corresponding nth measurement signal according to the sequence S1n corresponding to the synchronization channel. FIG. 15 is a schematic view of a pattern according to an embodiment of the present invention. Referring to FIG. 15, FIG. 15 shows the pattern of physical resource block pairs, the power is P1n and the received RSRP is RSRP1n.

Furthermore, the series corresponding to the N synchronization channels corresponding to cell 2 are in the first time unit, the second time unit, the nth time unit, the mth time unit, and the Nth time unit, respectively. There are S21, S22, S2n, S1m and S2N.

UE1 can find the mth synchronization channel of cell 2 by searching, and can determine information such as the pattern and power of the mth measurement signal corresponding to the mth synchronization channel according to S1m. FIG. 16 is a schematic view of another pattern according to the embodiment of the present invention. Referring to FIG. 16, the power is P1m and the received RSRP is RSRP2m.

As described above, UE1 acquires the measurement signals of N cells and compares the measurement signals of N cells. Each cell has at least two measurement signals, and the UE measures only one of the signals. For example, N = 2. The base station in cell 1 transmits N synchronization signals. Since UE1 detects the nth synchronization signal, the nth measurement signal corresponding to the nth synchronization signal is measured, and RSRP1n is obtained. The base station in cell 2 transmits M synchronization signals. Since the mth synchronization signal is detected, the mth measurement signal corresponding to the mth synchronization signal is measured, and RSRP2m is obtained.

UE1 compares RSRP1n with RSRP2m. If RSRP1n> RSRP2m, UE1 selects cell 1, otherwise it selects cell 2.

Step 4: The UE receives the nth broadcast channel corresponding to the nth synchronization channel, and the time frequency resource of the nth broadcast channel has a correspondence with the nth synchronization channel.

Specifically, the above-mentioned UE1 will be taken as an example. Assume that UE1 selects cell 1 and performs synchronization with cell 1 based on the nth synchronization channel. Then, the base station in cell 1 notifies the UE of the sequence, time-frequency resource, power information, etc. used for random access using the nth broadcast channel. For example, the base station in cell 1 uses the nth broadcast channel, the sequence group used for random access is sequence group n, and the sequences contained in sequence group n are (Pn1, Pn2, Png, ..., PnG), notifying the UE that the time-frequency resource for transmitting the random access preamble is (tn, fn), where t is the time domain. It is a resource, and f is a frequency domain resource. For example, the base station in cell 1 uses the mth broadcast channel to inform UE1 of the sequence group m used for random access, and the sequences contained in the sequence group m are (Pm1, Pm2, Pmg, ..., PmG), and the time-frequency resource for transmitting the random access preamble is (tm, fm), where t is the time resource and f is the frequency resource. is there. That is, the content on the N broadcast channels transmitted in one radio frame in one cell may be different, or the UE transmission sequence information does not need to be communicated using the broadcast channel. (T _n , f _n ) and (P _n1 , P _n2 , P _ng , ..., P _nG ) are coupled to the downlink sync signal S _{1 n.} (T _m , f _m ) and (P _m1 , P _m2 , P _mg , ..., P _mG ) are coupled to the downlink synchronization signal S _{1 m.}

The program may be stored on a computer-readable storage medium. When the program is executed, the steps of the embodiment of the method are executed. The storage medium includes an arbitrary medium that can store a program code such as a ROM, RAM, a magnetic disk, and an optical disk.

Finally, the aforementioned embodiments are for explaining the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will appreciate the above embodiments without departing from the spirit and scope of the technical solutions of the embodiments of the present invention.
