For example, the path loss of 3.5GHz frequency is 7-9 dB higher than the path loss of 1.8GHz frequency on average; the TDD frame structure with 2.5ms double period is adopted, and the uplink coverage performance is 5.2dB lower than that of FDD.

The base station can enable the terminal to adopt different transmitting antennas to transmit uplink signals in different time resources or frequency resources by allocating the transmitting antennas, thereby improving the uplink coverage rate in an airspace.
For example, the embodiment in fig. 2 may be utilized to assign transmit antennas.
FIG. 2 illustrates a flow diagram for some embodiments of step 110 in FIG. 1.
As shown in fig. 2, in step 1110, the transmit diversity scheme and the transmission scheme currently used are obtained. For example, the transmission mode includes at least one of whether frequency hopping (frequency hopping) transmission is turned on and whether repetition (repetition) transmission is turned on.
In step 1120, corresponding transmitting antennas are allocated to the terminal on different communication resources according to at least one of the currently adopted transmit diversity scheme and the transmission scheme.
In some embodiments, when the open loop transmit diversity mode is currently adopted, and frequency hopping transmission is not started, but repeat transmission is started, corresponding transmit antennas are allocated to different physical resource blocks in a certain time slot for repeat transmission; and according to the allocation result, allocating corresponding transmitting antennas for different physical resource blocks in other time slots for repeated transmission. Step 1120 may be implemented, for example, by the embodiments in fig. 3a, 3 b.
Fig. 3a illustrates a schematic diagram of some embodiments of step 1120 in fig. 2.
As shown in fig. 3a, the terminal has two antennas Tx1 and Tx2, and currently adopts an open loop transmit diversity mode; the currently adopted transmission mode is to turn off frequency hopping transmission and turn on repeat transmission.
Due to the adoption of repeated transmission, corresponding transmitting antennas can be allocated to different PRBs (Physical Resource blocks) in one slot. With reference to this slot, each PRB in the other slots is allocated a corresponding transmit antenna.
Fig. 3b illustrates a schematic diagram of some embodiments of step 1120 in fig. 2.
As shown in fig. 3b, the terminal has 4 antennas including Tx1, Tx2, Tx3, and Tx4, and currently, an open-loop transmit diversity scheme is adopted; the currently adopted transmission mode is to turn off frequency hopping transmission and turn on repeat transmission.
Due to the repeated transmission, corresponding transmitting antennas can be allocated for different PRBs in one of the time slots. With reference to this slot, each PRB in the other slots is assigned a corresponding transmit antenna.
In some embodiments, when the open-loop transmit diversity mode is currently used, and frequency hopping transmission is not turned on, but repetition transmission is turned on, a corresponding transmit antenna is allocated to each different time slot for repetition transmission. Step 1120 may be implemented, for example, by the embodiments in fig. 3c, 3 d.
Fig. 3c shows a schematic diagram of some embodiments of step 1120 in fig. 2.
As shown in fig. 3c, the terminal has two antennas Tx1 and Tx2, and currently, the open loop transmit diversity mode is adopted; the currently adopted transmission mode is to turn off frequency hopping transmission and turn on repeat transmission.
Different antennas may be allocated to adjacent time slots, respectively. For example, each PRB in the same slot may use the same antenna.
Fig. 3d shows a schematic diagram of some embodiments of step 1120 in fig. 2.
As shown in fig. 3d, the terminal has 4 antennas including Tx1, Tx2, Tx3, and Tx4, and currently, an open-loop transmit diversity scheme is adopted; the currently adopted transmission mode is to turn off frequency hopping transmission and turn on repeat transmission.
Different antennas may be allocated for different time slots, respectively. For example, each PRB in the same slot may use the same antenna.
In some embodiments, when open loop transmit diversity is currently used, inter-slot frequency hopping transmission is turned on, and retransmission is turned on, corresponding transmit antennas are respectively allocated to available physical resource blocks in each different slot for retransmission. Step 1120 may be implemented, for example, by the embodiments in fig. 3e, 3 f.
Fig. 3e shows a schematic diagram of some embodiments of step 1120 in fig. 2.
As shown in fig. 3e, the terminal has two antennas Tx1 and Tx2, and currently, the open loop transmit diversity mode is adopted; the currently adopted transmission mode is to start inter-slot (inter-slot) frequency hopping transmission and start repeated transmission.
Since inter-slot frequency hopping transmission is turned on, available frequency resources in adjacent slots are different, and thus different antennas can be allocated to adjacent slots. For example, the same antenna is used for the available PRBs in the same slot.
Fig. 3f shows a schematic diagram of some embodiments of step 1120 in fig. 2.
As shown in fig. 3f, the terminal has 4 antennas including Tx1, Tx2, Tx3, and Tx4, and currently, an open-loop transmit diversity method is adopted; the currently adopted transmission mode is to start time-slot frequency hopping transmission and start repeated transmission.
Since inter-slot frequency hopping transmission is enabled, the available frequency resources in different time slots are different, and therefore different antennas can be allocated to different time slots. For example, the same antenna is used for the available PRBs in the same slot.
In some embodiments, when an open-loop transmit diversity mode is currently used, frequency hopping transmission in a time slot is started, and repeat transmission is started, corresponding transmit antennas are allocated to different available physical resource blocks in each time resource included in a certain time slot for repeat transmission; and according to the allocation result, allocating corresponding transmitting antennas for different available physical resource blocks in each time resource contained in other time slots for repeated transmission. Step 1120 may be implemented, for example, by the embodiments in fig. 3g, 3 h.
Fig. 3g illustrates a schematic diagram of some embodiments of step 1120 in fig. 2.
As shown in fig. 3g, the terminal has two antennas Tx1 and Tx2, and currently, the open loop transmit diversity mode is adopted; the currently adopted transmission mode is intra-slot (intra-slot) frequency hopping transmission and repeated transmission is started.
Because the frequency hopping transmission in the time slot is started, the available frequency resources of the adjacent time resources in the same time slot are different, and therefore different antennas can be allocated to the adjacent time resources.
Due to the repeated transmission, the time slot can be referred to, and corresponding transmitting antennas can be allocated to each PRB in other time slots.
Fig. 3h shows a schematic diagram of some embodiments of step 1120 in fig. 2.
As shown in fig. 3h, the terminal has 4 antennas including Tx1, Tx2, Tx3, and Tx4, and currently, an open-loop transmit diversity scheme is adopted; the currently adopted transmission mode is frequency hopping transmission in an open time slot and repeated transmission is started.
Because the frequency hopping transmission in the time slot is started, the available frequency resources of the adjacent time resources in the same time slot are different, and therefore different antennas can be allocated to the adjacent time resources.
Due to the repeated transmission, the time slot can be referred to, and corresponding transmitting antennas can be allocated to each PRB in other time slots.
In some embodiments, when the open-loop transmit diversity mode is currently used, and frequency hopping transmission in a time slot is turned on, but repeated transmission is turned off, corresponding transmit antennas are allocated to available physical resource blocks in time resources included in different time slots, respectively. Step 1120 may be implemented, for example, by the embodiments in fig. 3i, 3 j.
FIG. 3i illustrates a schematic diagram of some embodiments of step 1120 in FIG. 2.
As shown in fig. 3i, the terminal has two antennas Tx1 and Tx2, and currently, an open loop transmit diversity mode is adopted; the currently adopted transmission mode is to start frequency hopping transmission in a time slot and close repeated transmission.
Because the frequency hopping transmission in the time slot is started, the available frequency resources of the adjacent time resources in the same time slot are different, and therefore different antennas can be allocated to the adjacent time resources.
The available PRBs in adjacent time slots are different, so different antenna allocation manners may be adopted to allocate antennas for the available PRBs in adjacent time slots.
FIG. 3j illustrates a schematic diagram of some embodiments of step 1120 in FIG. 2.
As shown in fig. 3j, the terminal has 4 antennas including Tx1, Tx2, Tx3, and Tx4, and currently, an open-loop transmit diversity scheme is adopted; the currently adopted transmission mode is to start frequency hopping transmission in a time slot and close repeated transmission.
Because the frequency hopping transmission in the time slot is started, the available frequency resources of the adjacent time resources in the same time slot are different, and therefore different antennas can be allocated to the adjacent time resources.
The available PRBs in different time slots are different, so different antenna allocation manners may be used to allocate antennas for the available PRBs in different time slots.
In some embodiments, when the open loop transmit diversity mode is currently used, and frequency hopping transmission is turned off, but repetitive transmission is turned on, corresponding transmit antennas are allocated to different subcarriers in a certain time slot for repetitive transmission; and according to the allocation result, allocating corresponding transmitting antennas for different subcarriers in other time slots for repeated transmission. Step 1120 may be implemented, for example, by the embodiment in fig. 3 k.
Fig. 3k shows a schematic diagram of some embodiments of step 1120 in fig. 2.
As shown in fig. 3k, the terminal has two antennas Tx1 and Tx2, and currently, the open loop transmit diversity mode is adopted; the currently adopted transmission mode is to turn off frequency hopping transmission and turn on repeat transmission.
Since the repeated transmission is turned on, corresponding transmit antennas may be allocated for different subcarriers in one of the time slots. With reference to the time slot, each subcarrier in the other time slots is assigned a corresponding transmit antenna.
In some embodiments, in the case of currently employing a closed-loop transmit diversity scheme, corresponding transmit antennas are respectively allocated to different time slots. Step 1120 may be implemented, for example, by the embodiment in fig. 3 l.
FIG. 3l illustrates a schematic diagram of some embodiments of step 1120 in FIG. 2.
As shown in fig. 3l, the terminal has 4 antennas, namely Txa, Txb, Txc, and Txd, and currently adopts a closed-loop transmit diversity mode. Different transmit antennas may be allocated for different time slots.
In some embodiments, in the case of currently adopting a closed-loop transmit diversity mode, corresponding transmit antennas are allocated to different physical resource blocks in each time slot. Step 1120 may be implemented, for example, by the embodiment in fig. 3 m.
Fig. 3m illustrates a schematic diagram of some embodiments of step 1120 in fig. 2.
As shown in fig. 3m, the terminal has 4 antennas, namely Txa, Txb, Txc, and Txd, and currently adopts a closed-loop transmit diversity mode. Different transmit antennas may be allocated for different PRBs in each time slot, respectively.
After the transmit antennas are assigned, other steps in fig. 1 may be used to direct the uplink transmission.
In step 120, according to the currently used transmit diversity scheme, the result of allocating the transmit antennas is transmitted to the terminal by using the signaling corresponding to the transmit diversity scheme. And the terminal adopts a corresponding transmitting antenna to transmit the uplink signal.
In some embodiments, in the case of currently adopting the open loop transmit diversity mode, the base station transmits the allocation result of the transmit antennas to the terminal by using higher layer signaling. For example, an antenna pattern (pattern) corresponding to the allocation result is transmitted to the terminal by using higher layer signaling.
For example, the higher layer signaling includes RRC (Radio Resource Control) signaling, MAC (Media Access Control) signaling, and the like.
In some embodiments, the base station utilizes physical layer signaling to schedule the transmit antennas of the terminals in the current closed loop transmit diversity mode.
In some embodiments, when the terminal transmits an uplink signal (PUCCH, PUSCH, etc.), different transmit antennas are used for different time instants or frequency resources. Under the condition of adopting open loop transmit diversity, the network informs the terminal of a pattern of a preset transmit antenna distribution result through a high-level signaling, and the terminal adopts a corresponding transmit antenna to send an uplink signal according to the pattern. Under the condition of closed-loop transmit diversity, the network dynamically schedules the transmitting antenna of the terminal through the physical layer signaling, and the terminal adopts the corresponding transmitting antenna to transmit the uplink signal according to the indication of the physical layer signaling.
Fig. 4 illustrates a block diagram of some embodiments of an apparatus for transmission of an upstream signal of the present disclosure.
As shown in fig. 4, the uplink signal transmission device 4 includes an allocation unit 41 and a transmission unit 42.
The allocating unit 41 allocates the corresponding transmitting antennas to the terminals on different communication resources, where the communication resources include at least one of time resources and frequency resources.
In some embodiments, the allocating unit 42 allocates the corresponding transmitting antennas to the terminals on different communication resources according to at least one of the currently adopted transmit diversity mode and the transmission mode. The transmission mode includes at least one of whether frequency hopping transmission is turned on or not and whether repeat transmission is turned on or not.
The transmission unit 42 transmits the allocation result of the transmitting antenna to the terminal by using the signaling corresponding to the transmit diversity mode according to the currently adopted transmit diversity mode, so that the terminal transmits the uplink signal by using the corresponding transmitting antenna.
In some embodiments, the transmitting unit 42 transmits the allocation result of the transmitting antenna to the terminal by using higher layer signaling under the condition of currently adopting the open loop transmit diversity mode. For example, the transmission unit 42 transmits an antenna pattern corresponding to the allocation result to the terminal by using higher layer signaling.
In some embodiments, the transmission unit 42 schedules the transmit antennas of the terminals using physical layer signaling in the case of currently employing closed loop transmit diversity.
