Description

Electronic device and method for wireless communication, computer readable storage medium

This application claims the priority of the Chinese patent application filed on March 12, 2021 with the application number 202110270987.9 and the invention title "Electronic device and method for wireless communication, computer-readable storage medium", all of which are The contents are incorporated herein by reference.

technical field

The present disclosure relates to the technical field of wireless communication, and in particular, to a base station indicating information about a timing advance to a user equipment. More specifically, it relates to an electronic device and method for wireless communication, and a computer-readable storage medium.

Background technique

In the wireless communication environment, timing advance (TA, Timing advance) is generally used for uplink transmission of user equipment, which means to estimate the radio frequency transmission delay caused by distance in order to make the uplink transmission packet of user equipment arrive at the base station at the desired time. The packets are sent out in advance of the corresponding time.

TA errors may cause inter-symbol-interfering (ISI, inter-symbol-interfering) at the base station. FIG. 1 is a schematic diagram illustrating inter-symbol interference due to timing advance in the prior art. As shown in Figure 1, there are four user equipments UE#0, UE#1, UE#2 and UE#3. For UE#0, the starting point of the base station receiver's receive window (eg, the Fourier Transform (FFT) window) falls exactly within the CP (Cyclic Prefix) of the symbols received from UE#0, and therefore does not cause ISI interference, the base station can correctly decode the desired signal. For UE#1, since there is a large difference between the TA received by UE#1 from the base station and the TA it actually needs (that is, there is a TA error), the starting point of the receiving window of the base station receiver falls on the base station from UE#1. The received symbols are outside the CP, thus causing ISI interference and the base station may not be able to correctly decode the desired signal. Similarly, the symbols received by the base station from UE#2 and UE#3 also cause ISI interference. When the ISI is too large to a certain extent, it will cause decoding errors, resulting in decoding failures, reducing the transmission efficiency of the user equipment, and affecting the user experience.

The faster the TA changes, the easier it is to generate TA errors. Therefore, in the scene where the TA changes rapidly (for example, the relative position between the base station and the UE is constantly changing due to the movement of the base station, which leads to the scene where the TA changes very frequently. For another example, in the high-speed rail, airplane and other fast UE moving scenarios , due to the movement of the UE, the relative position between the base station and the UE is constantly changing, resulting in a scenario where the TA changes very frequently), how the base station indicates the TA to the user equipment becomes an urgent problem to be solved.

Furthermore, it should also be appreciated that while development work can be very complex and time consuming, such development work would be a routine undertaking for those skilled in the art having the benefit of this disclosure.

Here, it should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only the equipment structures and/or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, and are omitted. other details not relevant to the present invention.

FIG. 2 shows a functional block diagram of an electronic device for wireless communication according to an embodiment of the present disclosure.

As shown in FIG. 2, the electronic device 200 includes: a pre-configuration unit 201, which can pre-configure setting information, wherein the setting information indicates whether to dynamically send the timing advance of the user equipment to the user equipment within the service range of the electronic device 200 and the control unit 203, which can control the uplink transmission of the user equipment based on the setting information.

The pre-configuration unit 201 and the control unit 203 may be implemented by one or more processing circuits, and the processing circuits may be implemented as chips, for example.

The electronic device 200 can be used as a network-side device in a wireless communication system, and specifically, for example, can be set on the base station side or communicably connected to the base station. Here, it should also be pointed out that the electronic device 200 may be implemented at the chip level, or may also be implemented at the device level. For example, the electronic device 200 may function as the base station itself, and may also include external devices such as memory, transceivers (not shown). The memory can be used to store programs and related data information that the base station needs to execute to implement various functions. The transceiver may include one or more communication interfaces to support communication with different devices (eg, user equipment, other base stations, etc.), and the implementation form of the transceiver is not particularly limited here.

The wireless communication system according to the present disclosure may be a 5G NR (New Radio) communication system. Further, the wireless communication system according to the present disclosure may include a non-terrestrial network (NTN). Optionally, the wireless communication system according to the present disclosure may further include a terrestrial network (TN). In addition, those skilled in the art can understand that the wireless communication system according to the present disclosure may also be a 4G or 3G communication system.

As an example, in the case where the electronic device 200 is a low-orbit satellite, since the low-orbit satellite moves faster, the TA changes faster. Therefore, the setting information can be used to indicate that information about the timing advance of the user equipment is to be sent to the user equipment. However, when the electronic device 200 is a geostationary satellite, since the moving speed of the geostationary satellite is slower, the TA changes more slowly, so the setting information can be used to indicate that the information about the timing advance of the user equipment is not sent to the user equipment. As another example, in the case of terrestrial network communication, if the user equipment (eg, in-vehicle equipment) moves at a relatively high speed, the TA changes rapidly, and the electronic device 200 may indicate through the setting information to send information about the user equipment to the user equipment. If the user equipment moves at a low speed, the TA changes slowly, and the electronic device 200 may indicate through the setting information not to send the information about the timing advance of the user equipment to the user equipment. It can be seen that the electronic device 200 according to this embodiment can dynamically indicate to the user equipment information about the timing advance of the user equipment according to the setting information.

In the prior art, the base station does not pre-configure the setting information about the timing advance. However, the electronic device 200 according to the embodiment of the present disclosure can pre-configure the setting information about the timing advance, and can control the uplink transmission of the user equipment based on the setting information.

As an example, the pre-configuration unit 201 may be configured to carry the setting information through Radio Resource Control (RRC) signaling. For example, the pre-configuration unit 201 may configure new RRC parameters such as DynamicTACommond to carry the above-mentioned setting information. Those skilled in the art should understand that, in addition to the RRC signaling, there are other signaling carrying the setting information, which will not be described here.

As an example, the control unit 203 may be configured to send information about the timing advance to the user equipment when the setting information is valid, so that the user equipment can dynamically update the timing advance and perform uplink transmission based on the updated timing advance . For example, when the above parameter DynamicTACommond is enabled, the control unit 203 sends information about the timing advance to the user equipment, so that the user equipment can dynamically update its timing advance; when the above parameter DynamicTACommond is disabled, the control unit 203 does not send the information to the user. The device sends information about the timing advance.

The following first describes how the electronic device 200 sends information about the timing advance to the user equipment quickly and timely, so that the user equipment can dynamically update the timing advance.

As an example, the control unit 203 may be configured to send the information on the timing advance through Downlink Control Information (DCI) signaling for uplink scheduling. Those skilled in the art should understand that, in addition to the DCI signaling, there are other signaling for quickly and timely sending the information about the timing advance, which will not be described here.

In the prior art, the base station performs TA update for each user equipment at the timing advance group (TAG) level through the medium access control control element (MAC CE), and the MAC CE is included in the physical downlink shared channel (PDSCH) for transmission, PDSCH needs hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback, and uplink scheduling is carried in DCI for transmission, so even if the uplink scheduling is performed in the next time slot after the TA command is sent, when the round-trip delay (RTD) is longer When it is large, it will also bring about the problem of TA failure. Especially in the scenario where the TA changes rapidly, the notification of MAC CE may not be timely enough, which will cause a greater delay in user scheduling and cause more serious ISI, reduce the transmission efficiency of the user, and thus reduce the user experience.

For the convenience of comparison, FIG. 3 shows the information interaction diagram in the prior art in which the base station sends the information about the timing advance to the user equipment through the medium access control control element, and FIG. 4 shows the information interaction diagram according to the embodiment of the present disclosure. , an information interaction diagram in which the electronic device 200 sends the information about the timing advance to the user equipment through the downlink control information.

The information interaction involved in Figure 3 is first described. In S30, the base station receives the scheduling request from the user equipment; in S31, the base station informs the user equipment to send a buffer status report (BSR) through DCI; in S32, the base station receives the BSR from the user equipment; The downlink control channel (PDCCH) and PDSCH send information about the timing advance to the user equipment (as mentioned above, the MAC CE is included in the PDSCH for transmission); in S34, the base station receives an acknowledgment (ACK) from the user equipment; In S35, the base station informs the user equipment to transmit data through DCI; in S36, the base station receives uplink data transmission from the user equipment.

Next, the information interaction involved in FIG. 4 is described. In S40, the electronic device 200 receives the scheduling request from the user equipment; in S41, the electronic device 200 informs the user equipment to send the BSR through DCI; in S42, the electronic device 200 receives the BSR from the user equipment; in S43, the base station passes The DCI sends information about the timing advance to the user equipment and informs the user equipment to transmit data; in S44, the base station receives the uplink data transmission from the user equipment.

It can be seen from the above description that the electronic device 200 according to the embodiment of the present disclosure can dynamically send information about the timing advance to the user equipment through DCI signaling, so that the user equipment can quickly and timely update its information about the timing advance, thereby Improve the data throughput of the user equipment, reduce the data transmission delay of the user equipment, and improve the user experience.

As an example, the information about the timing advance may include a difference between the current timing advance of the user equipment and the previous timing advance of the user equipment determined by the electronic device 200 . For example, assuming that the electronic device 200 determines that the current timing advance of the user equipment is TA_new, and the electronic device 200 calculates that the difference between the current timing advance TA_new and the previous timing advance TA_old of the user equipment is TA_DCI, the electronic device 200 will TA_DCI is sent to the user equipment as information about the timing advance. The user equipment calculates its current timing advance TA_new=TA_old+TA_DCI based on its previous timing advance TA_old and the received TA_DCI, and uses the TA_new value for current uplink transmission.

As an example, the information about the timing advance may include a time-related offset value determined by the electronic device 200 between the current timing advance of the user equipment and the previous timing advance of the user equipment. For example, assuming that the time-related offset value determined by the electronic device 200 is TA_drift, the electronic device 200 sends TA_drift as the information about the timing advance to the user equipment. The user equipment calculates its current timing advance TA_new=TA_old+Time*TA_drift based on its previous timing advance TA_old and the received TA_drift (where Time represents the time interval), then the user equipment uses the TA_new value to perform the current timing advance. upstream transmission.

The value of the previous timing advance TA_old mentioned above is the value for a certain TAG or a certain cell or a certain beam. notified/updated.

As an example, the information on the timing advance may include the current timing advance of the user equipment determined by the electronic device 200 . For example, assuming that the current timing advance determined by the electronic device 200 is TA_new, the electronic device 200 sends TA_new to the user equipment. The user equipment uses the TA_new value for current uplink transmission.

As an example, the information on the timing advance also includes the timing advance group TAG and/or the ID of the cell related to the timing advance. For example, the ID of the TAG may indicate which TAG the TA value is for, and one TAG may contain the IDs of one or more cells. When the TA is notified/updated in units of cells, the ID of the TAG may be replaced with the ID of the cell. In the above manner, the electronic device 200 can explicitly notify the user equipment of the timing advance group TAG and/or the ID of the cell related to the timing advance.

In order to reduce the overhead of signaling carrying the information about the timing advance, the signaling may not explicitly indicate which TAG and/or cell the information about the timing advance is for.

As an example, the control unit 203 may be configured to indicate the information about the timing advance group and/or cell related to the timing advance through the information about the timing advance group and/or cell in the signaling carrying the information about the timing advance ID. As mentioned above, the signaling carrying the information about the timing advance may be, for example, DCI. For example, the user equipment may be implicitly notified of which TAG and/or cell the information about the timing advance is for through the TAG information and/or cell information where the scheduled time-frequency resource blocks are located in the DCI signaling.

Furthermore, as an example, the control unit 203 may be configured to indicate the ID of the beam related to the timing advance through the information on the beam in the signaling carrying the information on the timing advance. For example, the user equipment may be implicitly informed of which beam the timing advance information is for through the beam ID indicated in the DCI signaling (eg, Transmission Configuration Indication (TCI), SRS Resource Indication (SRI), etc.).

Next, it is described how the electronic device 200 schedules the user equipment based on the timing advance of the user equipment.

FIG. 5 is a diagram illustrating an example of a scenario of movement of the electronic device 200 and distribution of user devices according to an embodiment of the present disclosure.

As shown in FIG. 5, including four user equipments UE#1-UE#4, the electronic device 200 is shown in FIG. 5 as a satellite. For example, at time T1', UE#2 is located directly below the satellite (the included angle between the satellite beam and UE#2 is 90°), and the included angles between UE#1 and UE#3 and the satellite beam are, for example, 100° and 80°, respectively. °, the included angle between UE#4 at the edge of the satellite cell/beam and the satellite beam is, for example, 70°. The satellite is moving away from UE#3 and UE#4. Those skilled in the art can understand that the scenario in FIG. 5 is only an example and not a limitation, and the following description is not limited to the scenario shown in FIG. 5 .

At this time, the satellite uses the point where the center of the satellite beam is vertically mapped to the ground as a reference point, and sends information about the timing advance (for example, including the current timing advance of the user equipment, the current timing advance of the user equipment) to the above four user equipments. At least one of the difference between the timing advance of the user equipment and the previous timing advance of the user equipment, and the time-related offset value between the current timing advance of the user equipment and the previous timing advance of the user equipment), usually Next, since the above four user equipments are located in the same area, the satellite sends the same information about the timing advance to the four user equipments each time.

6A and 6B respectively show exemplary diagrams of states in which signals transmitted from the user equipment arrive at the electronic device 200 at different times. Those skilled in the art can understand that FIGS. 6A and 6B are only examples and not limitations. In FIGS. 6A and 6B , the electronic device 200 is taken as an example of a satellite and the satellite sends the current TA of the user equipment to the user equipment as an example for description. It is assumed that FIG. 6A corresponds to the signal arrival state at time T1 ′, and FIG. 6B corresponds to The signal arrives at the state at time T2', where T2' is later than T1'. It should be noted that, for convenience, the following description takes the receiving window of the receiver of the base station (satellite) and the CP of the symbol to be received by the base station as an example. However, those skilled in the art can understand that there are other indicators for Analysis of ISI, here is no longer exhaustive.

As shown in Figure 5, since UE#2 is located directly below the satellite, the current TA it receives from the satellite is exactly equal to its required TA value. Therefore, at time T1' in Figure 6A, the receiving window of the satellite receiver is equal to The starting point falls exactly at the end point of the CP of the symbol received from UE#2; however, UE#1, UE#3 and UE#4 have received TA from the satellite because the current TA is less than their actual required TA value (a TA error occurs). ), the ending point of the CP of the symbols received by the satellite receiver from these user equipments is later than the starting point of the receiving window of the satellite receiver, but since the starting point of the receiving window of the satellite receiver falls within the Within the CP range, ISI will not be caused, so the satellite receiver can correctly decode the desired signals received from UE#1 to UE#4.

As the satellite moves away from UE#3 and UE#4 and/or the channel conditions change, as shown in Figure 6B, the distance between UE#1 and the satellite at time T2' compared to time T1' decreases, so the gap between the current TA received by UE#1 from the satellite and its actual required TA decreases, the start point of the satellite receiver's receiving window is closer to the end point of the CP of the symbol received from UE#1 and the satellite The starting point of the receiver's receiving window still falls within the CP range of the symbol received from UE#1, so it will not cause ISI; compared to T1' time, at time T2', the distance between UE#2 and the satellite increases, so there is a gap between the current TA received by UE#2 from the satellite and its actual required TA (timing advance error), although the CP of the symbol received by the satellite receiver from UE#2 ends later than the satellite receives. However, since the starting point of the receiving window of the satellite receiver still falls within the CP range of the symbol received from UE#2, it will not cause ISI; compared with time T1', at time T2' , the distance between UE#3 and the satellite increases, so the current TA received by UE#3 from the satellite is smaller than the TA it actually needs, although the end point of the CP of the symbol received by the satellite receiver from UE#3 is more later than the starting point of the receiving window of the satellite receiver, but because the starting point of the receiving window of the satellite receiver still falls within the CP range of the symbol received from UE#3, it will not cause ISI; compared to time T1', At time T2', the distance between UE#4 and the satellite increases, so the current TA received by UE#4 from the satellite is smaller than the TA it actually needs, not only the CP of the symbol received by the satellite receiver from UE#4 The end point of the satellite receiver is later than the start point of the receive window of the satellite receiver and the start point of the CP of the symbol received by the satellite receiver from UE#4 is also later than the start point of the receive window of the satellite receiver, resulting in a The starting point does not fall within the CP range of the symbol received from UE#4, so the information of other symbols is introduced into the receiving window of the satellite receiver, which will generate ISI, and the satellite receiver cannot correctly decode the received symbol from UE#4. The desired signal, that is, among UE#1 to UE#4, UE#4 will have the greatest impact on the inter-symbol interference at the satellite receiver.

As can be seen from the above description, if the user equipment that has a large impact on the inter-symbol interference at the satellite receiver (for example, the user equipment at the edge of the satellite cell/beam (for example, UE#4)) is not scheduled in time, the user equipment receives the signal from the satellite. The gap between the received TA and the TA actually required will become larger and larger, which will cause ISI or lead to more serious ISI, reduce the transmission efficiency of the user equipment, increase the scheduled delay, and thus reduce the user experience.

FIG. 7 shows a functional block diagram of an electronic device 200 for wireless communication according to another embodiment of the present disclosure. Optimally, as shown in FIG. 7 , the electronic device 200 according to another embodiment of the present disclosure may further include a calculation unit 705 and a scheduling unit 707, and the calculation unit 705 may calculate the scheduling factor related to the timing advance of the user equipment, and the scheduling Unit 707 may schedule the user equipment based on the scheduling factor.

The computing unit 705 and the scheduling unit 707 may be implemented by one or more processing circuits, and the processing circuits may be implemented as chips, for example.

In the prior art, the base station does not consider the timing advance of the user equipment when scheduling the user equipment. However, the electronic device 200 according to the embodiment of the present disclosure can schedule the user equipment based on the timing advance of the user equipment, and can timely schedule the user equipment that has a great influence on the inter-symbol interference at the receiver of the electronic device 200 (for example, in (user equipment at the satellite cell/beam edge), avoid or reduce ISI, improve the transmission efficiency of the user equipment, reduce the scheduling delay of the user equipment, and thus improve the user experience.

As an example, the calculating unit 705 may be configured to calculate the time length for scheduling based on the arrival time of the data arriving at the electronic device 200 and the starting point of the receiving window of the electronic device 200 in the case where the user equipment performs uplink transmission with the current timing advance, And the calculation unit 705 may be configured to calculate the scheduling factor based on the length of time.

The following first describes the situation in which the timing advance sent by the electronic device 200 to the user equipment is smaller than the timing advance required by the user equipment. A situation of inter-symbol interference has occurred at the receiver of 200.

As described above, if the starting point of the receiving window of the receiver of the electronic device 200 falls within the CP of the received symbol, ISI interference will not be caused. However, if a timing advance error occurs because the predetermined timing advance provided by the electronic device 200 to the user equipment is smaller than the timing advance required by the user equipment, the CP of the symbol arriving at the electronic device 200 when the user equipment performs uplink transmission with the predetermined timing advance The starting point is later in time than the starting point of the receiving window of the receiver of the electronic device 200 (see UE#4 in FIG. 6B ), which may cause ISI interference, thereby causing the electronic device 200 to fail to correctly decode the data received from the user equipment. As can be seen from the above description, if the starting point of the CP of the symbol arriving at the electronic device 200 when the user equipment performs uplink transmission with a predetermined timing advance is later than the starting point of the receiving window of the receiver of the electronic device 200, then because the predetermined timing advance The difference between the timing advance amount and the timing advance actually required by the user equipment (ie, the timing advance is wrong) will cause the electronic device 200 to fail to correctly decode the symbols received from the user equipment.

8A is a diagram illustrating a situation where the timing advance sent by the electronic device 200 to the user equipment is smaller than the timing advance required by the user equipment and ISI has not yet occurred at the receiver of the electronic device 200, according to an embodiment of the present disclosure, and A diagram of an example of the time length for scheduling corresponding to each user equipment. For comparison, in FIG. 8A , in addition to the user equipments UE#1, UE#3 and UE#4 whose current timing advance received from the electronic device 200 is smaller than their actual required timing advance, it is also shown that there is currently no User equipment UE#2 with timing advance error. As shown in FIG. 8A , it is shown that the starting point of the receiving window of the receiver of the electronic device 200 is Etime. In addition, in the following, when the user equipment performs uplink transmission with the current timing advance, the arrival time of the data arriving at the electronic device 200 is simply referred to as the "arrival time corresponding to the current timing advance". 8A respectively shows: the “arrival time corresponding to the current timing advance” Ctime1_A of the data received by the electronic device 200 from UE#1 (ie, the starting point of the CP corresponding to UE#1), the electronic device 200 from The "arrival time corresponding to the current timing advance" Ctime2_A of the data received by UE#2 (ie, the starting point of the CP corresponding to UE#2), the "arrival time corresponding to the current timing advance" of the data received by the electronic device 200 from UE#3 The corresponding arrival time "Ctime3_A" (ie, the starting point of the CP corresponding to UE#3), the "arrival time corresponding to the current timing advance" Ctime4_A of the data received by the electronic device 200 from UE#4 (ie, with UE#4 the starting point of the corresponding CP). For each user equipment UE#1 to UE#4, the difference between the start point Etime of the receiving window of the receiver of the electronic device 200 and its "arrival time corresponding to the current timing advance" is, for example, the value corresponding to the electronic device. length of time. For example, the difference between Etime and Ctime1_A is the time length TL1_A corresponding to UE#1; the difference between Etime and Ctime2_A is, for example, the time length TL2_A corresponding to UE#2; the difference between Etime and Ctime3_A is, for example, the time length corresponding to UE#3 TL3_A; the difference between Etime and Ctime4_A is, for example, the time length TL4_A corresponding to UE#4. It can be seen from FIG. 8A that the relationship between the time lengths corresponding to each electronic device is as follows: TL4_A is the smallest, TL2_A is the largest, and TL1_A and TL3_A may be equal. In this case, since the time length TL4_A corresponding to UE#4 is the shortest, it means that among UE#1 to UE#4, UE#4 is most likely to cause ISI due to TA error, so UE#4 should be scheduled in time. Combining with the situation of FIG. 8A, it can be known that as the time length for scheduling is shorter, the scheduling factor is larger.

FIG. 8B is a diagram illustrating a situation in which the timing advance sent by the electronic device 200 to the user equipment is less than the timing advance required by the user equipment and intersymbol interference has occurred at the receiver of the electronic device 200 according to an embodiment of the present disclosure. A diagram of an example of the time length for scheduling corresponding to each user equipment. For comparison, in FIG. 8B , except for user equipments UE#3 and UE# whose current timing advance received from electronic device 200 is smaller than its actual required timing advance and thus has caused intersymbol interference at the receiver of electronic device 200 In addition to 4, it also shows that the user equipment UE#2 shown in FIG. 8A does not currently have a timing advance error and that the current timing advance received from the electronic device 200 is smaller than its actual required timing advance but has not yet caused. User equipment UE#1 with inter-symbol interference. Reference numerals related to UE#1 and UE#2 in FIG. 8B refer to the description of FIG. 8A , which will not be repeated here. In FIG. 8B , the “arrival time corresponding to the current timing advance” of the data received by the electronic device 200 from UE#3 is Ctime3_B (ie, the starting point of the CP corresponding to UE#3), and the electronic device 200 receives the data from UE#4 The "arrival time corresponding to the current timing advance" of the received data is Ctime4_B (ie, the starting point of the CP corresponding to UE#4). In FIG. 8B , for the user equipments UE#3 and UE#4, the difference between the “arrival time corresponding to the current timing advance” and the starting point Etime of the receiving window of the receiver of the electronic device 200 is, for example, the difference between the The length of time corresponding to the device. For example, the difference between Ctime3_B and Etime is the time length TL3_B corresponding to UE#3; the difference between Ctime4_B and Etime is the time length TL4_B corresponding to UE#4. Since UE#3 and UE#4 have caused inter-symbol interference at the receiver of the electronic device 200, among UE#1 to UE#4, UE#3 and UE#4 (ie, with UE#3) are preferentially scheduled The scheduling factor corresponding to UE#4 is larger), while for UE#3 and UE#4, the inter-symbol interference due to UE#4 is larger (ie, the time length TL4_B corresponding to UE#4 is larger than that of UE#4). The time length TL3_B corresponding to UE#3), therefore, the electronic device 200 schedules UE#4 preferentially (ie, the scheduling factor corresponding to UE#4 is the largest).

FIG. 8C is a diagram illustrating a situation in which the timing advance sent by the electronic device 200 to the user equipment is greater than the timing advance required by the user equipment, so that intersymbol interference occurs at the receiver of the electronic device 200, and each A diagram of an example of a time length for scheduling corresponding to a user equipment.

It can be seen from FIG. 8C that the current timing advance received by UE#1 and UE#2 from the electronic device 200 is larger than the actual required timing advance. Therefore, the CP of the symbols received by the electronic device 200 from UE#1 and UE#2 The end points of both are earlier than the start of the receive window of the receiver of the electronic device 200, thus causing ISI at the receiver of the electronic device 200 as shown in the figure.

For comparison, in FIG. 8C , except for user equipments UE#1 and UE# whose current timing advance received from electronic device 200 is larger than its actual required timing advance and thus has caused intersymbol interference at the receiver of electronic device 200 2 (for example, the length of the inter-symbol interference caused by UE#1 is greater than the length of the inter-symbol interference caused by UE#2, that is, the length of the ISI corresponding to UE#1 in FIG. 8C is greater than the length of the ISI corresponding to UE#2) In addition, it also shows the user equipment UE#3 shown in FIG. 8A that the current timing advance received from the electronic device 200 is smaller than its actual required timing advance but has not caused inter-symbol interference, and the user equipment UE#3 shown in FIG. 8B The current timing advance received from the electronic device 200 is smaller than its actual required timing advance and the user equipment UE#4 that has caused ISI (for example, the length of the ISI caused by UE#1 is smaller than the symbol caused by UE#4 inter-interference length, that is, the length of the ISI corresponding to UE#1 in FIG. 8C is greater than the length of the ISI corresponding to UE#4).

8C respectively shows: the "arrival time corresponding to the current timing advance" Ctime1_C of the data received by the electronic device 200 from the UE#1 (ie, the starting point of the CP corresponding to the UE#1), the electronic device 200 from the UE#1 The "arrival time corresponding to the current timing advance" Ctime2_C of the data received by UE#2 (ie, the starting point of the CP corresponding to UE#2), the "arrival time corresponding to the current timing advance" of the data received by the electronic device 200 from UE#3 The corresponding arrival time "Ctime3_C" (ie, the starting point of the CP corresponding to UE#3), the "arrival time corresponding to the current timing advance" Ctime4_C of the data received by the electronic device 200 from UE#4 (ie, with UE#4 the starting point of the corresponding CP).

In FIG. 8C , for the user equipments UE#1 and UE#2, for example, the difference between the start point Etime of the receiving window of the receiver of the electronic device 200 and its "arrival time corresponding to the current timing advance" can be calculated first. difference value, and then add the calculated difference value to the length of the CP (assuming CPL) as the time length corresponding to the electronic device, and the time length can reflect the difference between the user equipment UE#1 and UE# 2 The length of the intersymbol interference caused. For example, time length TL1_C=Etime-Ctime1_C+CPL corresponding to UE#1, and time length TL2_C=Etime-Ctime2_C+CPL corresponding to UE#2. Referring to FIG. 8A , it can be seen that the time length TL3_C=Etime−Ctime3_C corresponding to UE#3. Referring to FIG. 8B , it can be seen that the time length TL4_C=Ctime4_C-Etime corresponding to UE#4. Since UE#1, UE#2 and UE#4 have caused inter-symbol interference at the receiver of the electronic device 200, among UE#1 to UE#4, UE#1, UE#2 and UE#4 have The scheduling priority is higher than that of UE#3. For UE#1, UE#2 and UE#4, the user equipment with greater inter-symbol interference caused by priority scheduling, because TL4_C>TL1_C>TL2_C, therefore, the scheduling priority of UE#4>UE#1 The scheduling priority of > UE#2's scheduling priority (ie, the scheduling factor corresponding to UE#4 > the scheduling factor corresponding to UE#1 > the scheduling factor corresponding to UE#2).

FIG. 9 is a diagram illustrating an example of scheduling a user equipment by the electronic device 200 according to an embodiment of the present disclosure. FIG. 9 is described in conjunction with the user equipments UE#1 to UE#4 in FIG. 8A. As can be seen from FIG. 8A , among the user equipments UE#1 to UE#4 that have not yet caused ISI, since the time length corresponding to UE#4 at the satellite cell/beam edge is the shortest, UE#4 is most likely to cause ISI due to TA errors. , therefore, as shown in FIG. 9 , the electronic device 200 preferentially schedules UE#4.

FIG. 10 is a diagram illustrating an example of scheduling user equipment at different times according to an embodiment of the present disclosure. FIG. 10 is described in conjunction with the user equipments UE#1 to UE#4 in FIG. 8A. In Fig. 10, the four user equipments UE#1 to UE#4 in Fig. 8A are shown, and the TA conditions of UE#1 to UE#4 during time T1-T8 are shown, with UE#4 For example, "TA ok" at time T4 indicates that if UE#4 is scheduled at time T4, the timing advance of UE#4 will not cause ISI to be generated at electronic device 200, while "T ANG" at time T5 indicates that If UE#4 was scheduled at time T5, the timing advance of UE#4 would cause an ISI to be generated at the electronic device 200. In FIG. 10, it is assumed that the electronic device 200 receives scheduling requests from UE#2 and UE#4. With reference to FIG. 8A , since the time length corresponding to UE#4 is the shortest, the electronic device 200 will schedule UE#4 preferentially. Assuming that the electronic device 200 schedules UE#4 preferentially in T4, as shown in FIG. 10, UE#4 is "TA ok" at time T4, the timing advance of UE#4 will not cause ISI to be generated at the electronic device 200. In addition, even if UE#2 is scheduled later than UE#4 (eg, UE#2 is scheduled at T5), since UE#2 is "TA ok" at times T5-T8, the timing advance of UE#2 Nor does it result in ISI being generated at the electronic device 200 . Conversely, if the timing advance of the user equipment is not considered, UE#4 may be scheduled in T5, as shown in Figure 10, UE#4 is "T ANG" in time T5, then the timing advance of UE#4 This can result in ISI being generated at the electronic device 200 .

As an example, the length of time is also related to the decoding capability of the electronic device 200 in the presence of intersymbol interference.

In the description in conjunction with FIG. 8A , it is assumed that the starting point of the CP of the symbol arriving at the electronic device 200 coincides with the starting point of the receiving window of the receiver of the electronic device 200 when the user equipment performs uplink transmission. 200, the data received from the user equipment may not be correctly decoded. Taking UE#4 as an example, in FIG. 8A, the time length corresponding to UE#4 can be represented as Etime-Ctime4_A. However, when the receiver of the electronic device 200 is capable, even if the user equipment performs uplink transmission, the starting point of the CP of the symbol reaching the electronic device 200 is later than the starting point of the receiving window of the receiver of the electronic device 200 by a predetermined value in time. (for example, within a predetermined ratio (for example, 10%) of the length of the CP), that is, there is a certain ISI (for example, the ISI within 10%, or the ISI ratio is within 10%), the received data can also be decoded correctly. For data, still take UE#4 as an example, in this case, the time length corresponding to UE#4 can be expressed as the length of Etime-Ctime4_A+CP x a predetermined ratio. In addition, for the situations described in conjunction with FIGS. 8B-8C, the time length of the user equipment is also related to the decoding capability of the electronic device 200 in the case of inter-symbol interference, which is not repeated here.

As an example, the computing unit 705 may be configured to be based on at least one of the location of the user equipment, the angle between the electronic device 200 and the user equipment, whether the user equipment is close to handover, and the size of the data packet when the user equipment performs uplink transmission , calculate the scheduling factor. In this way, the electronic device 200 can, based on at least one of the position of the user equipment, the angle between the electronic device and the user equipment, whether the user equipment is close to handover, and the size of the data packet when the user equipment performs uplink transmission, to The user equipment performs scheduling.

As an example, the user equipment includes multiple user equipments, and the scheduling unit 707 may be configured to schedule the user equipment with the largest scheduling factor among the multiple user equipments. That is, the electronic device 200 may schedule the user equipment directly based on the scheduling factor.

In addition, the electronic device 200 may also schedule the user equipment based on the scheduling factor in combination with other factors. As an example, the scheduling unit 707 may be configured to calculate the ratio between the currently requested communication rate and the cumulative average communication rate of each user equipment, calculate the product of the ratio and the scheduling factor, and schedule, among the plurality of user equipments, The user equipment with the largest product.

Assuming that the scheduling factor of user equipment i (1≤i≤N, N is the total number of user equipments) is TAF _i , R _i (t) is the communication rate requested by user equipment i at time t, and T _i (t) is the user equipment The cumulative average communication rate of i at time t, the scheduled user equipment k can be expressed as:

In expression (1),

means to take

maximum i value.

In this way, the electronic device 200 schedules the user equipment considering not only the scheduling factor related to the timing advance of the user equipment, but also the current requested communication rate and the cumulative average communication rate of the user equipment.

The present disclosure also provides an electronic device for wireless communication according to another embodiment. FIG. 11 shows a functional block diagram of an electronic device 1100 for wireless communication according to another embodiment of the present disclosure. As shown in FIG. 11 , the electronic device 1100 includes: a processing unit 1101 , which can receive preconfigured setting information from a network-side device that provides services to the electronic device 1100 , wherein the setting information indicates whether the network-side device wants to dynamically report to the electronic device 1100 and the communication unit 1103, which can perform uplink transmission based on the setting information.

The processing unit 1101 and the communication unit 1103 may be implemented by one or more processing circuits, and the processing circuits may be implemented as chips, for example.

The electronic device 1100 may, for example, be provided on the user equipment (UE) side or be communicatively connected to the user equipment. Here, it should also be noted that the electronic device 1100 may be implemented at the chip level, or may also be implemented at the device level. For example, the electronic device 1100 may function as a user device itself, and may also include external devices such as a memory, a transceiver (not shown in the figure), and the like. The memory can be used to store programs and related data information that the user equipment needs to execute to achieve various functions. The transceiver may include one or more communication interfaces to support communication with different devices (eg, base stations, other user equipment, etc.), and the implementation form of the transceiver is not particularly limited here. The base station may be, for example, an eNB or a gNB.

As an example, the network-side device may be a base station, for example, the network-side device may be the electronic device 200 according to an embodiment of the present disclosure.

In the prior art, the user equipment does not receive the setting information about the timing advance preconfigured by the base station from the base station. However, the electronic device 1100 according to the embodiment of the present disclosure can receive setting information about the timing advance preconfigured by the network-side device, and can perform uplink transmission based on the setting information.

As an example, the processing unit 1101 may be configured to receive setting information through radio resource control (RRC) signaling. For example, the processing unit 1101 may receive the above setting information through RRC parameters such as DynamicTACommond. Those skilled in the art should understand that the processing unit 1101 may receive the above-mentioned setting information through other signaling except RRC signaling, which will not be repeated here.

As an example, the processing unit 1101 may be configured to receive information about the timing advance from the network side device when the setting information is valid, so as to dynamically update the timing advance and perform uplink transmission based on the updated timing advance. For example, when the above parameter DynamicTACommond is enabled, the processing unit 1101 receives information about the timing advance from the network-side device; when the above-mentioned parameter DynamicTACommond is disabled, the processing unit 1101 does not receive information about the timing advance from the network-side device.

As an example, the processing unit 1101 may be configured to receive information on timing advance through Downlink Control Information (DCI) signaling for uplink scheduling.

According to the embodiment of the present disclosure, the electronic device 1100 can dynamically receive information about the timing advance from the network-side device through DCI signaling, so that the electronic device 1100 can quickly and timely update its information about the timing advance, thereby improving the electronic equipment. 1100 data throughput, reducing the data transmission delay of the electronic device 1100 and improving the user experience. It should be understood by those skilled in the art that the processing unit 1101 can also receive information about the timing advance in a fast and timely manner through other signaling, which will not be repeated here.

As an example, the processing unit 1101 may be configured to update the timing advance by the difference between the current timing advance of the electronic device 1100 and the previous timing advance of the electronic device 1100 included in the information about the timing advance. For example, assuming that the network side device determines that the current timing advance of the electronic device 1100 is TA_new, and the network side device calculates the difference between the current timing advance TA_new and the previous timing advance TA_old of the electronic device 1100 as TA_DCI, then the network side The device sends the TA_DCI to the electronic device 1100 as information on the timing advance. The electronic device 1100 calculates its current timing advance TA_new=TA_old+TA_DCI based on its previous timing advance TA_old and the received TA_DCI, so as to update the timing advance, and use the TA_new value for current uplink transmission.

As an example, the processing unit 1101 may be configured to pass a time-related offset value between the current timing advance of the electronic device 1100 and the previous timing advance of the electronic device 1100, which is included in the information about the timing advance, Update the timing advance. For example, assuming that the time-related offset value determined by the network-side device is TA_drift, the network-side device sends TA_drift as the information about the timing advance to the electronic device 1100 . The electronic device 1100 calculates its current timing advance TA_new=TA_old+Time*TA_drift (where Time represents a time interval) based on its previous timing advance TA_old and the received TA_drift, thereby updating the timing advance, and The electronic device 1100 uses the TA_new value for the current uplink transmission.

As an example, the processing unit 1101 may be configured to update the timing advance by the current timing advance of the electronic device 1100 included in the information about the timing advance. For example, assuming that the current timing advance determined by the network-side device is TA_new, the network-side device sends TA_new to the electronic device 1100 . The electronic device 1100 uses the TA_new value for the current uplink transmission.

As an example, the processing unit 1101 may be configured to update the timing advance based on the timing advance group TAG and/or the ID of the cell related to the timing advance also included in the information about the timing advance. The ID of the TAG may indicate which TAG the TA value is for, and the ID of the cell may indicate which cell the TA value is for. The processing unit 1101 may be configured to update the timing advance based on the TAG and/or the ID of the cell explicitly included in the information on the timing advance.

As an example, the processing unit 1101 may be configured to be based on the timing advance group and/or cell related to the timing advance indicated by the information about the timing advance group and/or cell in the signaling carrying the information about the timing advance ID, update timing advance. As described above, the electronic device 1100 may receive information about the timing advance, eg, through DCI signaling. For example, the electronic device 1100 may know which TAG and/or cell the information about the timing advance is for through the TAG information and/or the cell information where the scheduled time-frequency resource block is located in the DCI signaling.

As an example, the processing unit 1101 may be configured to update the timing advance based on the ID of the beam related to the timing advance indicated by the information about the beam in the signaling carrying the information about the timing advance. For example, the electronic device 1100 may know which beam the information about the timing advance is for through the beam ID (eg, Transmission Configuration Indication (TCI), SRS Resource Indication (SRI), etc.) indicated in the DCI signaling.

In the process of describing the electronic device for wireless communication in the above embodiments, it is apparent that some processes or methods are also disclosed. In the following, a summary of these methods is given without repeating some of the details already discussed above, but it should be noted that although these methods are disclosed in the description of an electronic device for wireless communication, these methods do not necessarily employ Those components described may or may not necessarily be performed by those components. For example, embodiments of an electronic device for wireless communications may be implemented partially or entirely using hardware and/or firmware, while the methods for wireless communications discussed below may be implemented entirely by computer-executable programs, although these The method may also employ hardware and/or firmware of an electronic device for wireless communication.

In step S1204, setting information is pre-configured, wherein the setting information indicates whether the information about the timing advance of the user equipment is to be dynamically sent to the user equipment within the service range of the electronic device. In step S1206, the uplink transmission of the user equipment is controlled based on the setting information. Method S1200 ends at step S1208.

For example, the method may be performed by the electronic device 200 described above, and the specific details thereof can be referred to the description of the corresponding position above, which will not be repeated here.

In step S1304, preconfigured setting information is received from the network-side device providing services to the electronic device, wherein the setting information indicates whether the network-side device is to dynamically send information about the timing advance of the electronic device to the electronic device. In step S1306, uplink transmission is performed based on the setting information. Method S1300 ends at step S1308.

The method can be performed by, for example, the electronic device 1100 described above, and the specific details thereof can be found in the description of the corresponding position above, which will not be repeated here.

[About application examples of base stations]

(First application example)

14 is a block diagram illustrating a first example of a schematic configuration of an eNB or gNB to which techniques of this disclosure may be applied. Note that the following description takes an eNB as an example, but the same can be applied to a gNB. eNB 800 includes one or more antennas 810 and base station equipment 820. The base station apparatus 820 and each antenna 810 may be connected to each other via an RF cable.

Each of the antennas 810 includes a single or multiple antenna elements (such as multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna), and is used by the base station apparatus 820 to transmit and receive wireless signals. As shown in FIG. 14, eNB 800 may include multiple antennas 810. For example, multiple antennas 810 may be compatible with multiple frequency bands used by eNB 800. Although FIG. 14 shows an example in which the eNB 800 includes multiple antennas 810, the eNB 800 may also include a single antenna 810.

The base station apparatus 820 includes a controller 821 , a memory 822 , a network interface 823 , and a wireless communication interface 825 .

The controller 821 may be, for example, a CPU or a DSP, and operates various functions of a higher layer of the base station apparatus 820 . For example, the controller 821 generates data packets from data in the signal processed by the wireless communication interface 825 and communicates the generated packets via the network interface 823 . The controller 821 may bundle data from a plurality of baseband processors to generate a bundled packet, and deliver the generated bundled packet. The controller 821 may have logical functions to perform controls such as radio resource control, radio bearer control, mobility management, admission control and scheduling. This control may be performed in conjunction with nearby eNB or core network nodes. The memory 822 includes RAM and ROM, and stores programs executed by the controller 821 and various types of control data such as a terminal list, transmission power data, and scheduling data.

The network interface 823 is a communication interface for connecting the base station apparatus 820 to the core network 824 . The controller 821 may communicate with core network nodes or further eNBs via the network interface 823 . In this case, eNB 800 and core network nodes or other eNBs may be connected to each other through logical interfaces such as S1 interface and X2 interface. The network interface 823 may also be a wired communication interface or a wireless communication interface for wireless backhaul. If the network interface 823 is a wireless communication interface, the network interface 823 may use a higher frequency band for wireless communication than the frequency band used by the wireless communication interface 825 .

Wireless communication interface 825 supports any cellular communication scheme, such as Long Term Evolution (LTE) and LTE-Advanced, and provides wireless connectivity to terminals located in cells of eNB 800 via antenna 810. The wireless communication interface 825 may generally include, for example, a baseband (BB) processor 826 and RF circuitry 827 .

In place of the controller 821, the BB processor 826 may have some or all of the above-described logical functions. The BB processor 826 may be a memory storing a communication control program, or a module including a processor and associated circuitry configured to execute the program. The update procedure may cause the functionality of the BB processor 826 to change. The module may be a card or blade that is inserted into a slot of the base station device 820 . Alternatively, the module can also be a chip mounted on a card or blade. Meanwhile, the RF circuit 827 may include, for example, a mixer, a filter, and an amplifier, and transmit and receive wireless signals via the antenna 810 .

As shown in FIG. 14 , the wireless communication interface 825 may include multiple BB processors 826 . For example, multiple BB processors 826 may be compatible with multiple frequency bands used by eNB 800. As shown in FIG. 14 , the wireless communication interface 825 may include a plurality of RF circuits 827 . For example, multiple RF circuits 827 may be compatible with multiple antenna elements. Although FIG. 14 shows an example in which the wireless communication interface 825 includes multiple BB processors 826 and multiple RF circuits 827 , the wireless communication interface 825 may also include a single BB processor 826 or a single RF circuit 827 .

In the eNB 800 shown in FIG. 14 , when the electronic device 200 described with reference to FIG. 2 is implemented as a base station, its transceiver may be implemented by the wireless communication interface 825. At least a portion of the functionality may also be implemented by the controller 821 . For example, the controller 821 may perform the instruction of the information on the timing advance by executing the functions of the units described above with reference to FIG. 2 .

(Second application example)

15 is a block diagram illustrating a second example of a schematic configuration of an eNB or gNB to which techniques of this disclosure may be applied. Note that similarly, the following description takes an eNB as an example, but is equally applicable to a gNB. eNB 830 includes one or more antennas 840, base station equipment 850, and RRH 860. The RRH 860 and each antenna 840 may be connected to each other via RF cables. The base station apparatus 850 and the RRH 860 may be connected to each other via high-speed lines such as fiber optic cables.
