Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an antenna assembly and a terminal device. Background Art

[0002] SRS (Sounding Reference Signal) is a signal sent by a terminal device (such as a mobile phone) to a base station. In a TDD (Time Division Duplexing) system, it is used to evaluate the quality of the downlink so that the base station can better understand the signal propagation in the wireless environment and optimize data transmission.

[0003] In the SRS antenna rotation technology, if the terminal device has multiple antennas, it can send SRS signals through the antennas in different links in turn. In this way, the base station can collect information about the links on different antennas and perform link evaluation more accurately.

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0043] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0044] The present application provides an antenna assembly.

[0045] See also Figure 2 In the present application, the antenna assembly includes a switch device (ie Figure 2 K in), transceiver link (i.e. Figure 2 TR in), multiple receiving links (i.e. Figure 2 R in) and multiple antennas (i.e. Figure 2 ANT in );

[0046] One end of each switch device is connected to the transceiver link, the other end of each switch device is respectively connected to any receiving link, and each antenna is respectively connected to the output end of the transceiver link and the output end of the receiving link.

[0047] based on Figure 1 It can be seen that the conventional antenna assembly only supports 4-way antenna rotation (i.e. Figure 1 The transmit and receive link TR0 and receive link R0 connected by switch K in the figure can only send signals to the base station through the link. Correspondingly, the base station can only transmit signals through the antennas on the four links (i.e. Figure 1 The signal sent by ANT in the 4-way link is used to evaluate the downlink link of the 4-way link, but the other 4-way receiving link (i.e. Figure 1 R0' in the figure performs downlink evaluation, and thus fails to optimize the data transmission efficiency of the other 4 receiving links, and fails to ensure the communication quality of the other 4 receiving links.

[0048] Based on this, this embodiment proposes a new type of antenna assembly, which includes a switch device, a transceiver link, a receiving link and an antenna. Each transceiver link (ie Figure 2 TR in) and each receiving link (i.e. Figure 2 The connection relationship between the R in the figure enables the transmission signal transmitted on the transceiver link to be transmitted to any receiving link based on the turned-on switch device, and through the antenna on any receiving link (i.e. Figure 2 The ANT in the communication link sends the transmission signal to the base station, so that the base station can evaluate the downlink of any receiving link and optimize the data transmission efficiency of any receiving link, thereby ensuring the communication quality of all receiving links.

[0049] For details, see Figure 3 , the transceiver link includes multiple transceiver links (i.e. Figure 3 TR1~TRn in it);

[0050] Each transceiver link passes through the switch device (i.e. Figure 3 K) in each receiving link (i.e. Figure 3 R) in is connected.

[0051] based on Figure 2 , proposed Figure 3 An embodiment of an antenna transmission module is shown.

[0052] When there are multiple transceiver links, in order to ensure that the transmission signal on each transceiver link can be transmitted to each receiving link and avoid the defect that the link evaluation of individual receiving links cannot be performed due to the existence of a transmission signal on only one transceiver link and the transceiver link has not established a connection relationship with all the receiving links, this embodiment establishes that each transceiver link establishes a connection relationship with other receiving links through a switching device, so that the transmission signal transmitted on each transceiver link can be transmitted to the corresponding receiving link based on the established connection relationship, and the transmission signal is sent to the base station through the antenna connected to the corresponding receiving link, so that each antenna takes turns to transmit, ensure the link evaluation of each receiving link, and avoid the defect of decreased communication quality due to omission of link evaluation.

[0053] For details, see Figure 4 In the case where the antenna assembly has two transceiver signal ends, the transceiver link includes a first transceiver link TR1, the receiving link includes a first receiving link R1, and the switch device includes a first three-pole three-throw switch K1 and a first single-pole double-throw switch K2.

[0054] The first end of the first transceiver link TR1 is connected to the first transceiver signal end (i.e. Figure 4TX0 RX0), the second end of the first transceiver link TR1 is connected to the first input end of the first three-pole three-throw switch K1, and is connected to the first antenna ANT1 through the first output end of the first three-pole three-throw switch K1.

[0055] The first end of the first receiving link R1 is connected to the first receiving signal end (i.e. Figure 4 RX1 in the figure), the second end of the first receiving link R1 is connected to the second input end of the first three-pole three-throw switch K1, and is connected to the second antenna ANT2 through the second output end of the first three-pole three-throw switch K1.

[0056] The third output terminal of the first three-pole three-throw switch K1 is connected to the first input terminal of the first single-pole double-throw switch K2.

[0057] In order to explain the antenna assembly proposed in this embodiment in detail, the following is designed: Figure 4 The detailed antenna assembly is shown and described as follows.

[0058] The antenna assembly in this embodiment includes a first transceiver link TR1, a first receiving link R1, a first three-pole three-throw switch K1 and a first single-pole double-throw switch K2.

[0059] It should be noted that the three-pole three-throw switch refers to a switch using three contacts, and the link is switched by switching the connection between different input contacts and different output contacts. At this time, it is necessary to evaluate the link status of the first transceiver link TR1, so the first input contact of the first three-pole three-throw switch K1 is controlled to be connected to the first output contact, so that the first transmission signal received from the first transceiver signal end of the first transceiver link TR1 is transmitted to the first output end of the first three-pole three-throw switch K1 through the first input end of the first three-pole three-throw switch K1, and is transmitted to the first antenna ANT1 through the first output end of the first three-pole three-throw switch K1, and finally the first transmission signal is sent to the base station based on the first antenna ANT1, and the link evaluation of the first transceiver link TR1 is performed.

[0060] If it is necessary to evaluate the link status of the first receiving link R1 at this time, the first input contact of the first three-pole three-throw switch K1 is controlled to be connected to the second output contact, so that the first transmission signal connected to the first transceiver link TR1 from the first transceiver signal end is transmitted to the second output end of the first three-pole three-throw switch K1 through the first input end of the first three-pole three-throw switch K1, and is transmitted to the second antenna ANT2 connected to the first receiving link R1 through the second output end of the first three-pole three-throw switch K1. Finally, the first transmission signal is sent to the base station based on the second antenna ANT2 to perform link evaluation of the first receiving link R1.

[0061] The single-pole double-throw switch in this embodiment switches the links on other antenna link subunits by switching the connection between a single input contact and two different output contacts. For example, when the first input contact of the first three-pole three-throw switch K1 is controlled to be connected to the third output contact, the first transmission signal received by the first transceiver link TR1 from the first transceiver signal end can be transmitted to the first input end of the first single-pole double-throw switch K2 through the first input end and the third output end of the first three-pole three-throw switch K1, and the first transmission signal is transmitted to other receiving links through the first output end or the second output end of the first single-pole double-throw switch K2, thereby realizing the link evaluation of other receiving links by the base station.

[0062] Further, the transceiver link includes a second transceiver link TR2, the receiving link includes a second receiving link R2, and the switch device includes a second three-pole three-throw switch K3 and a second single-pole double-throw switch K4.

[0063] The first end of the second transceiver link TR2 is connected to the second transceiver signal end (i.e. Figure 4 TX1 RX1 in the figure), the second end of the second transceiver link TR2 is connected to the second input end of the second three-pole three-throw switch K3, and is connected to the third antenna ANT3 through the second output end of the second three-pole three-throw switch K3.

[0064] The first end of the second receiving link R2 is connected to the second receiving signal end (i.e. Figure 4 RX2 in the figure), the second end of the second receiving link R2 is connected to the third input end of the second three-pole three-throw switch K3, and is connected to the fourth antenna ANT4 through the third output end of the second three-pole three-throw switch K3.

[0065] A first output end of the second three-pole three-throw switch K3 is connected to a first input end of the second single-pole double-throw switch K4.

[0066] Specifically, the antenna assembly in this embodiment further includes a second transceiver link TR2, a second receiving link R2, a second three-pole three-throw switch K3 and a second single-pole double-throw switch K4.

[0067] Assuming that it is necessary to evaluate the link status of the second transceiver link TR2 at this time, the second input contact of the second three-pole three-throw switch K3 is controlled to be connected with the second output contact, so that the second transmission signal connected to the second transceiver link TR2 from the second transceiver signal end is transmitted to the second output end of the second three-pole three-throw switch K3 through the second input end of the second three-pole three-throw switch K3, and is transmitted to the third antenna ANT3 through the second output end of the second three-pole three-throw switch K3. Finally, the second transmission signal is sent to the base station based on the third antenna ANT3 to perform link evaluation of the second transceiver link TR2.

[0068] If it is necessary to evaluate the link status of the second receiving link R2 at this time, the second input contact of the second three-pole three-throw switch K3 is controlled to be connected to the third output contact, so that the second transmission signal connected to the second transceiver link TR2 from the second transceiver signal end is transmitted to the third output end of the second three-pole three-throw switch K3 through the second input end of the second three-pole three-throw switch K3, and is transmitted to the fourth antenna ANT4 connected to the second receiving link R2 through the third output end of the second three-pole three-throw switch K3. Finally, the second transmission signal is sent to the base station based on the fourth antenna ANT4 to perform link evaluation of the second receiving link R2.

[0069] When the second input contact of the second three-pole three-throw switch K3 is controlled to be connected to the first output contact, the second transmission signal connected to the second transceiver link TR2 from the second transceiver signal end can be transmitted to the first input end of the second single-pole double-throw switch K4 through the second input end and the first output end of the second three-pole three-throw switch K3, and the second transmission signal is transmitted to other receiving links through the first output end or the second output end of the second single-pole double-throw switch K4, thereby realizing link evaluation of other receiving links by the base station.

[0070] Further, the third input end of the first three-pole three-throw switch K1 is connected to the first output end of the second single-pole double-throw switch K4, and the first input end of the second three-pole three-throw switch K3 is connected to the second output end of the first single-pole double-throw switch K2.

[0071] It should be noted that the reason why the first transmission signal and the second transmission signal can be transmitted to other receiving links, that is, the reason why the transmission signal on a transceiver link can be transmitted to any receiving link, is that the output end of the first single-pole double-throw switch K2 connected to the first three-pole three-throw switch K1 establishes a connection relationship with the input end of the second three-pole three-throw switch K3, and at the same time, the output end of the second single-pole double-throw switch K4 connected to the second three-pole three-throw switch K3 establishes a connection relationship with the input end of the first three-pole three-throw switch K1.

[0072] by Figure 4 For example, assuming that the first input contact of the first three-pole three-throw switch K1 is controlled to be connected to the third output contact, and the first input contact of the first single-pole double-throw switch K2 is controlled to be connected to the second output contact, at this time, the first transmission signal received by the first transceiver link TR1 from the first transceiver signal end can be transmitted to the first input end of the first single-pole double-throw switch K2 through the first input end and the third output end of the first three-pole three-throw switch K1, and then transmitted to the first input end of the second three-pole three-throw switch K3 through the second output end of the first single-pole double-throw switch K2. At this time, by switching the contact connection relationship in the second three-pole three-throw switch K3, the first transmission signal is sent from the antenna corresponding to the second transceiver link TR2 and the second receiving link R2.

[0073] Assuming that the second input contact of the second three-pole three-throw switch K3 is controlled to be connected to the first output contact, and the first input contact of the second single-pole double-throw switch K4 is controlled to be connected to the first output contact, the second transmission signal connected to the second transceiver link TR2 from the second transceiver signal end can be transmitted to the first input end of the second single-pole double-throw switch K4 through the second input end and the first output end of the second three-pole three-throw switch K3, and then transmitted to the third input end of the first three-pole three-throw switch K1 through the first output end of the second single-pole double-throw switch K4. At this time, by switching the contact connection relationship in the first three-pole three-throw switch K1, the second transmission signal is sent from the antenna corresponding to the first transceiver link TR1 and the first receiving link R1.

[0074] Furthermore, the receiving link further includes a third receiving link R3 and a fourth receiving link R4, and the switch device further includes a third three-pole three-throw switch K5.

[0075] The first end of the third receiving link R3 is connected to the third receiving signal end (i.e. Figure 4 The second end of the third receiving link R3 is connected to the first input end of the third three-pole three-throw switch K5, and is connected to the fifth antenna ANT5 through the first output end of the third three-pole three-throw switch K5. The first end of the fourth receiving link R4 is connected to the fourth receiving signal end (i.e. Figure 4 RX4 in the figure), a second end of the fourth receiving link R4 is connected to a second input end of the third three-pole three-throw switch K5 and is connected to the sixth antenna ANT6 through a second output end of the third three-pole three-throw switch K5.

[0076] If it is necessary to add additional antennas based on the four antennas, for example, add a fifth antenna ANT5 and a sixth antenna ANT6 to receive signals sent by the base station, then Figure 4 As shown, the receiving links corresponding to the fifth antenna ANT5 and the sixth antenna ANT6 are respectively set to antenna links with the same structure as the first transceiver link TR1 and the first receiving link R1. The third input end of the third three-pole three-throw switch K5 is connected to the first output end of the first single-pole double-throw switch K2.

[0077] Assuming that the first transceiver link TR1 is accessing the first transmission signal at this time, and the link state of the third receiving link R3 needs to be evaluated at this time, the first input end contact of the first three-pole three-throw switch K1 is controlled to be connected to the third output end contact, and the first input end contact of the first single-pole double-throw switch K2 is controlled to be connected to the first output end contact, and the third input end contact of the third three-pole three-throw switch K5 is controlled to be connected to the first output end contact, so that the first transmission signal accessed from the first transceiver link TR1 to the first transceiver signal end is transmitted through the first input end of the first three-pole three-throw switch K1. To the third output end of the first three-pole three-throw switch K1, and transmit the first transmission signal to the first input end of the first single-pole double-throw switch K2 through the third output end of the first three-pole three-throw switch K1, after the first transmission signal is transmitted to the third input end of the third three-pole three-throw switch K5 through the first output end of the first single-pole double-throw switch K2, the first transmission signal is transmitted to the fifth antenna ANT5 via the first output end of the third three-pole three-throw switch K5, and finally the first transmission signal is sent to the base station based on the fifth antenna ANT5, and link evaluation of the third receiving link R3 is performed.

[0078] If it is necessary to evaluate the link status of the fourth receiving link R4 at this time, the first input end contact of the first three-pole three-throw switch K1 is controlled to be connected to the third output end contact, and the first input end contact of the first single-pole double-throw switch K2 is controlled to be connected to the first output end contact, and the third input end contact of the third three-pole three-throw switch K5 is controlled to be connected to the second output end contact, so that the first transmission signal received from the first transceiver link TR1 from the first transceiver signal end is transmitted to the third output end of the first three-pole three-throw switch K1 through the first input end of the first three-pole three-throw switch K1, and the first transmission signal is transmitted to the first input end of the first single-pole double-throw switch K2 through the third output end of the first three-pole three-throw switch K1, and the first transmission signal is transmitted to the third input end of the third three-pole three-throw switch K5 through the first output end of the first single-pole double-throw switch K2, and then the first transmission signal is transmitted to the sixth antenna ANT6 via the second output end of the third three-pole three-throw switch K5, and finally the first transmission signal is sent to the base station based on the sixth antenna ANT6 to perform link evaluation of the fourth receiving link R4.

[0079] In this way, link evaluation of the newly added third receiving link R3 and fourth receiving link R4 is achieved.

[0080] Furthermore, the receiving link further includes a fifth receiving link R5 and a sixth receiving link R6, and the switch device further includes a fourth three-pole three-throw switch K6.

[0081] The first end of the fifth receiving link R5 is connected to the fifth receiving signal end (ie Figure 4The second end of the fifth receiving link R5 is connected to the second input end of the fourth three-pole three-throw switch K6, and is connected to the seventh antenna ANT7 through the second output end of the fourth three-pole three-throw switch K6. The first end of the sixth receiving link R6 is connected to the sixth receiving signal end (i.e. Figure 4 RX6 in the figure), the second end of the sixth receiving link R6 is connected to the third input end of the fourth three-pole three-throw switch K6, and is connected to the eighth antenna ANT8 through the third output end of the fourth three-pole three-throw switch K6.

[0082] If it is necessary to add additional antennas based on the above 6 antennas, for example, add a seventh antenna ANT7 and an eighth antenna ANT8 to receive signals sent by the base station, then Figure 4 As shown, the receiving links corresponding to the seventh antenna ANT7 and the eighth antenna ANT8 are respectively set to antenna components with the same structure as the second transceiver link TR2 and the second receiving link R2. The first input end of the fourth three-pole three-throw switch K6 is connected to the second output end of the second single-pole double-throw switch K4.

[0083] Assuming that the second transceiver link TR2 is accessing the second transmission signal at this time, and the link state of the fifth receiving link R5 needs to be evaluated at this time, the second input end contact of the second three-pole three-throw switch K3 is controlled to be connected to the first output end contact, and the first input end contact of the second single-pole double-throw switch K4 is controlled to be connected to the second output end contact, and the first input end contact of the fourth three-pole three-throw switch K6 is controlled to be connected to the second output end contact, so that the second transmission signal accessed from the second transceiver link TR2 to the second transceiver signal end is transmitted through the second input end of the second three-pole three-throw switch K3. To the first output end of the second three-pole three-throw switch K3, and transmit the second transmit signal to the first input end of the second single-pole double-throw switch K4 through the first output end of the second three-pole three-throw switch K3, after the second transmit signal is transmitted to the first input end of the fourth three-pole three-throw switch K6 through the second output end of the second single-pole double-throw switch K4, the second transmit signal is transmitted to the seventh antenna ANT7 via the second output end of the fourth three-pole three-throw switch K6, and finally the second transmit signal is sent to the base station based on the seventh antenna ANT7 to perform link evaluation of the fifth receiving link R5.

Finally, the second transmission signal is sent to the base station based on the fifth antenna ANT5 to perform link evaluation of the third receiving link R3.

[0086] Further, assuming that the second transceiver link TR2 is accessing the second transmission signal at this time, and the link state of the sixth receiving link R6 needs to be evaluated, the first input end contact of the first three-pole three-throw switch K1 is controlled to be connected to the third output end contact, the first input end contact of the first single-pole double-throw switch K2 is controlled to be connected to the second output end contact, the first input end contact of the second three-pole three-throw switch K3 is controlled to be connected to the first output end contact, the first input end contact of the second single-pole double-throw switch K4 is controlled to be connected to the second output end contact, and the first input end contact of the fourth three-pole three-throw switch K6 is controlled to be connected to the third output end contact, so that the first transmission signal accessed by the first transceiver link TR1 from the first transceiver signal end is transmitted to the third output end of the first three-pole three-throw switch K1 through the first input end of the first three-pole three-throw switch K1, and is transmitted to the third output end of the first three-pole three-throw switch K1 through the first three-pole three The third output end of the single-pole double-throw switch K1 transmits the first transmission signal to the first input end of the first single-pole double-throw switch K2, and transmits the first transmission signal to the first input end of the second three-pole three-throw switch K3 through the second output end of the first single-pole double-throw switch K2. The first transmission signal is then transmitted to the first input end of the second single-pole double-throw switch K4 via the first output end of the second three-pole three-throw switch K3, and the first transmission signal is transmitted to the first input end of the fourth three-pole three-throw switch K6 via the second output end of the second single-pole double-throw switch K4. The first transmission signal is transmitted to the eighth antenna ANT8 through the third output end of the fourth three-pole three-throw switch K6. Finally, the first transmission signal is sent to the base station based on the eighth antenna ANT8, and the link evaluation of the sixth receiving link R6 is performed. This process is analogous to the link evaluation of each link in the antenna receiving link.

[0087] It should be noted that based on Figure 4 For the antenna assembly shown in the figure, if only four rounds of antenna transmission are needed at this time, it is only necessary to delete the connection relationship between the link that needs to be cut and the link that does not need to be cut. Figure 4 If there are still links that need to be added, the link can be easily added by simply connecting the new link with the same antenna link structure to the third output end of the third three-pole three-throw switch K5, that is, directly connecting the new link to the output end of the idle three-pole three-throw switch, so as to achieve the addition of antennas and link evaluation.
