Description

Communication method, terminal device and network device Technical Field
The present invention relates to the field of communications, and more particularly, to a communication method, a terminal device, and a network device.
Background
In most current mobile communications, a base station is used as a center, all UEs (User Equipment) are directly connected with the base station on an air interface, and a target UE is found through the relay of the base station to perform communications. The benefit of such communication is that the UE's behaviour in the network is controllable and the base station plays the role of a control centre. In some emerging applications, such as D2D (Device to Device) communication or V2X (Vehicle to everything, internet of vehicles), a UE may communicate directly with other UEs without going through a base station. This direct mode of communication between UEs is called SL (Sidelink) communication. The feature of sidestream communication is that the base station is no longer a control center and can communicate directly without a network. Interference may exist between SL communication and NR communication of a UE, and the SL communication of the UE may also have interference to a base station, so that interference needs to be reduced.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following description is given of related technologies of the embodiments of the present application, and the following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as an alternative, which all belong to the protection scope of the embodiments of the present application.
The internet of vehicles is an example of a sidestream communication. Fig. 2 is a schematic diagram of SL communication, and as shown in fig. 2, the vehicle-to-vehicle may communicate with a nearby vehicle SL for collision avoidance and other applications.
Sidestream communications may include a variety of different communications scenarios, such as: the terminal is within the coverage of the mobile communication network (in coverage scenario, 5G NR for example) or the terminal is outside the coverage of the mobile communication network (out of coverage scenario).
Fig. 3a and 3b are schematic diagrams of SL communication scenarios. As shown in fig. 3a, when the UE is in a mobile communication network coverage scenario, the UE will typically remain connected to the NR base station while also remaining SL connected to other UEs. As shown in fig. 3b, when the UE is in an out-of-coverage scenario of the mobile communication network, the UE is typically not in the coverage area of the NR base station, and the UE only has SL connection.
The following describes the contents concerning the transmission/reception timing.
In a communication system, a base station side has strict timing. Fig. 4 is a schematic diagram of base station and UE timing. As shown in fig. 4, base station gNB timing (timing) is a transmission/reception timing seen from the base station side.
Because the terminal and the base station have a certain distance, the signal transmitted by the base station can be received by the UE after a propagation delay of a certain time, and the embodiment is that the UE receiving time has a time delay compared with gNB timing. In fig. 4, downlink timing (DL) (UE) is shifted backward from gNB timing as a whole.
In order to avoid mutual interference caused by inconsistent time of uplink signals transmitted by a plurality of UEs in the same cell reaching a base station, the base station needs to adjust the transmission time of the UEs according to the distance. UEs that are far away require earlier advanced transmissions than UEs that are near away, so that the signals arriving at the base station arrive at approximately the same time as each other. As shown in fig. 4, the uplink timing (UE) is advanced by a certain time from both the gNB timing and the downlink timing (UE). The timing advance between downlink (UE) and Uplink (UE) is commonly referred to as TA (Timing advance).
And comparing the timing difference of the base station and the terminal receiving and transmitting signals under the condition of no TA and TA. It can be obtained that, under the condition of no TA, the uplink signals transmitted by different UEs received by the base station are in a dispersed state in time, and the uplink signals transmitted by different UEs after TA are adopted arrive at the base station end almost simultaneously.
The following describes the transmit-receive timing and interference for SL
In SL communication, when a UE is in the coverage of an NR cell (or called NR base station), examples of two types of SL timing are included:
fig. 5 is a schematic diagram of interference in a SL timing and NR UE Rx timing alignment scenario. As shown in fig. 5 (grey indicates active slots), for example, SL is consistent with UE Rx (receive) timing and SL can only operate in the uplink transmit slots. This results in a timing offset TA of the UE's transmit timing (Tx) from the timing of the SL. In such a timing structure, when the NR of the UE and the SL operate in the same frequency band, the NR transmitted signal interferes with the SL received signal (e.g., interferes with sl+sl1), and the SL transmitted signal (e.g., sl+sl1) will also interfere with the received signal of the base station.
Note that: SL2 is not affected by NR transmission nor by NR base station reception
Fig. 6 is a schematic diagram of interference in a SL timing and NR UE Tx timing alignment scenario. As shown in fig. 6 (grey indicates active slots), for example, SL remains consistent with UE transmit (Tx) timing and SL can only operate in the uplink transmit slots. This results in the UE's transmit (Tx) timing to be consistent with the timing of the SL. In this timing structure, when NR and SL operate in the same frequency band, the NR transmitted signal interferes with the SL received signal, and the SL transmitted signal will also interfere with the base station received signal
Various schemes may be provided by embodiments of the present application for interference involving NR and SL in the above SL timing mode.
Fig. 7 is a schematic flow chart diagram of a communication method 200 according to an embodiment of the present application. The method may alternatively be applied to the system shown in fig. 1, but is not limited thereto. The method includes at least some of the following.
S210, the terminal equipment reports the spectrum interval requirement between the new wireless (NR) uplink signal and the side uplink (SL) received signal. Wherein the spectrum interval requires scheduling for the NR uplink signal and the SL received signal. Optionally, the terminal device reports a minimum spectrum interval between the NR uplink signal and the SL received signal. Wherein the minimum spectrum interval is used for scheduling the NR uplink signal and the SL received signal.
In the embodiment of the present application, within a terminal device, a signal transmitted from the terminal device to a network device may be referred to as an NR uplink signal, and a signal received by the terminal device from another terminal device may be referred to as an SL reception signal. After the terminal device reports the spectrum interval requirement of the NR uplink signal and the SL received signal to the network device, the network device may schedule the NR uplink signal and the SL received signal based on the spectrum interval requirement, so that the actual spectrum interval between the NR uplink signal and the SL received signal is as greater than or equal to the spectrum interval requirement as possible.
Alternatively, in the embodiment of the present application, the spectrum interval requirement is a minimum spectrum interval between an NR uplink signal and a SL received signal required in a case where the NR and the SL operate simultaneously in the same frequency band.
Optionally, in an embodiment of the present application, the spectrum interval requirement includes at least one of:
a minimum spectral interval such that the NR uplink signal is transmitted at maximum power and does not cause interference to the SL received signal;
so that the NR uplink signal is transmitted at maximum power and the interference received by the SL received signal does not exceed a minimum spectral interval of a set value.
Optionally, in an embodiment of the present application, the method further includes:
in the case where the spectrum interval between the NR uplink signal and the SL received signal is smaller than the spectrum interval requirement, for example, a minimum spectrum interval, the terminal apparatus performs transmission of the NR uplink signal and reception of the SL received signal by using a time division duplex (Time Division Duplexing, TDD) scheme.
For example, if the actual spectrum interval between the NR uplink signal and the SL received signal is smaller than the minimum spectrum interval, the transmission of the NR uplink signal and the reception of the SL received signal by the terminal device may not be performed simultaneously, but a TDD scheme is adopted.
Optionally, in an embodiment of the present application, the method further includes:
in the case where the spectrum interval between the NR uplink signal and the SL received signal is smaller than the spectrum interval requirement, for example, a minimum spectrum interval, if the terminal apparatus performs transmission of the NR uplink signal and reception of the SL received signal at the same time, the SL received sensitivity of the terminal apparatus deteriorates.
Illustratively, if the actual spectrum interval between the NR upstream signal and the SL received signal is smaller than the minimum spectrum interval, and the transmission of the NR upstream signal and the reception of the SL received signal by the terminal apparatus are performed simultaneously, in this case, the SL received sensitivity of the terminal apparatus may be allowed to deteriorate. Further, the SL reception sensitivity deterioration of the terminal device may be controlled according to a certain deterioration value.
Optionally, in an embodiment of the present application, the determining manner of the degradation value of the SL receiving sensitivity degradation includes at least one of the following manners:
predefining the degradation value using a criterion;
the terminal device reports the degradation value.
In this embodiment, the terminal device reports the spectrum interval requirement, for example, the minimum spectrum interval, so that the network device can be prompted to avoid interference by adopting a larger spectrum interval as much as possible when scheduling the carrier spectrum.

Optionally, in this embodiment of the present application, the spectrum interval requirement is a minimum spectrum interval between the NR uplink signal and the SL received signal required for the NR and the SL to operate simultaneously in the same frequency band.
Optionally, in an embodiment of the present application, the spectrum interval requirement includes at least one of:
a minimum spectral interval such that the NR uplink signal is transmitted at maximum power and does not cause interference to the SL received signal;
So that the NR uplink signal is transmitted at maximum power and the interference received by the SL received signal does not exceed a minimum spectral interval of a set value.
Optionally, in an embodiment of the present application, the method further includes:
in the case where the spectral separation between the NR uplink signal and the SL received signal is less than the spectral separation requirement, e.g., a minimum spectral separation, the network device transmits a rotation time template for the NR uplink signal and the received SL received signal. The time template may specify the specific manner in which the transmission of the NR upstream signal and the reception of the SL received signal are not performed simultaneously. For example, transmission of an NR uplink signal and reception of an SL reception signal are alternately performed by time slots.
Optionally, in an embodiment of the present application, the method further includes:
in the case that the spectrum interval between the NR uplink signal and the SL received signal is smaller than the spectrum interval requirement, for example, a minimum spectrum interval, the network device allows the SL received sensitivity of the terminal device to be deteriorated, and the terminal device is a terminal device reporting the spectrum interval requirement.
Optionally, in an embodiment of the present application, the determining manner of the degradation value of the SL receiving sensitivity degradation includes at least one of the following manners:
Predefining the degradation value using a criterion;
and receiving the deterioration value reported by the terminal equipment.

Fig. 9 is a schematic flow chart diagram of a communication method 400 according to another embodiment of the present application. The method may alternatively be applied to the system shown in fig. 1, but is not limited thereto. The method includes at least some of the following.
S410, the terminal device reports the maximum power capability of the new wireless NR uplink signal corresponding to the degradation value that causes degradation of the reception sensitivity of the side uplink SL.
In the embodiment of the present application, within a terminal device, a signal transmitted from the terminal device to a network device may be referred to as an NR uplink signal, and a signal received by the terminal device from another terminal device may be referred to as an SL reception signal. The terminal device reports the maximum power capability of the NR uplink signal corresponding to the degradation value that causes the degradation of the SL receiving sensitivity to the network device, and the network device may schedule the NR uplink signal and the SL receiving signal of the terminal device according to the maximum power capability, so that the transmitting power of the NR uplink signal of the terminal device is as less than or equal to the maximum power capability as possible. In this way, by reporting the maximum power capability of the NR uplink signal corresponding to the degradation value, the network device can schedule the transmit power of the NR uplink signal without causing an excessive performance loss of the SL received signal, so as to reduce interference between the SL received signal and the NR uplink signal.
Optionally, in an embodiment of the present application, the method further includes: the terminal device reports the degradation value. Specifically, the terminal device may report the degradation value and the maximum power capability in a combined manner, or may report the degradation value and the maximum power capability separately. The network device may schedule the NR uplink signal and the SL received signal of the terminal device according to the maximum power capability, so that the transmit power of the NR uplink signal of the terminal device is as smaller than or equal to the maximum power capability corresponding to the actual degradation value of the terminal device as possible. In this way, by reporting the degradation value and the maximum power capability of the corresponding NR uplink signal, the network device can schedule the transmit power of the NR uplink signal without causing excessive performance loss of the SL received signal, so as to reduce interference between the SL received signal and the NR uplink signal.
Optionally, in an embodiment of the present application, the degradation value is a predefined value. For example, the correspondence relation between the maximum power capability of the terminal device and the deterioration value is respectively stored in the terminal device and the network device.
Optionally, in an embodiment of the present application, the method further includes: the terminal device disconnects the NR connection and/or disconnects the SL connection in case the transmit power exceeds the maximum power capability and the degradation value exceeds a threshold. The threshold value of the degradation value has an indirect relation to the maximum power capability. The base station may schedule the transmit power of the UE according to the transmit power capability corresponding to the terminal sensitivity degradation value acceptable by itself, but the determination of the threshold value is not directly related to the maximum power, but may be determined according to the sensitivity degradation condition.
For example, if the actual transmission power of the terminal device exceeds the maximum power capability and the actual deterioration value of the SL reception sensitivity deterioration of the terminal device exceeds the threshold, the terminal device may disconnect the NR connection with the network, may disconnect the SL connection with other terminal devices, and may disconnect the NR connection and the SL connection.

For example, the network device and the terminal device may agree that when the SL reception sensitivity deteriorates beyond a threshold, the NR connection is disconnected.

Fig. 11 is a schematic flow chart diagram of a communication method 600 according to another embodiment of the present application. The method may alternatively be applied to the system shown in fig. 1, but is not limited thereto. The method includes at least some of the following.
S610, the terminal equipment acquires the transmission power requirement of the network equipment on the terminal equipment, wherein the transmission power requirement is associated with the position information. Optionally, the terminal device obtains a maximum transmission power allowed by the network device for the terminal device, where the maximum transmission power is associated with the location information.

The terminal device may, for example, limit the transmit power of its own SL transmit signal to be less than the transmit power requirements described above, e.g., less than the maximum transmit power.
Optionally, in the embodiment of the present application, the location information includes information of a grid area, and the terminal device obtains a transmission power requirement of the network device on the terminal device, including:
the terminal equipment acquires the transmission power requirement corresponding to the information of the grid area where the terminal equipment is located, wherein the transmission power requirement is the maximum transmission power of the terminal equipment allowed by the network equipment.
For example, the coverage area of the network device is divided into a plurality of grid areas in advance, and each grid area has the maximum transmission power allowed by the corresponding network device. The terminal equipment moves to the coverage area of a certain network equipment, and the network equipment can broadcast and send the corresponding relation between the grid area and the maximum transmitting power to the terminal equipment. Only the grid area where the terminal equipment is currently located and the corresponding maximum transmitting power can be sent; the correspondence of all grid areas of the network device to the maximum transmit power may also be transmitted. There may be a case where a plurality of grid areas correspond to the same maximum transmission power. After the terminal equipment moves to a certain grid area, the corresponding maximum transmitting power can be obtained according to the identification of the grid area where the terminal equipment is currently located, and the actual transmitting power of the terminal equipment, such as the actual transmitting power of the SL transmitting signal, is limited to be smaller than the maximum transmitting power.

The reference geographic location information may be, for example, geographic location information of the network device, or other pre-set geographic location information. The geographical location information of the network device may be latitude and longitude information of the base station, and since the location information of the base station is unchanged, the information may be sent by using separate broadcasting, so as to save signaling overhead, and of course, may also be sent together with the maximum transmission power.
Optionally, in the embodiment of the present application, the terminal device controls the transmission power based on the maximum transmission power allowed by the network device, including: the terminal device limits the transmit power to be less than the maximum transmit power allowed by the network device for the terminal device.

Optionally, the maximum transmit power associated with the location information is predefined or received from the network device. For example, the correspondence of distance to maximum transmit power is predefined or received from the network device. For another example, the correspondence of the grid to the maximum transmit power is predefined or received from the network device.
Specifically, after the terminal device calculates the distance from the network device, the correspondence between the distance and the maximum transmission power may be searched to determine the maximum transmission power allowed by the network device in the case of the distance. The terminal device may then define its own transmit power to be less than the maximum transmit power.
In this embodiment, the terminal device receives the maximum transmission power of the terminal device allowed by the network device, where the transmission power requirement is associated with the location information, and the transmission power of the terminal device may be limited to be less than the maximum transmission power, so as to reduce interference caused by excessive transmission power of the terminal device to the network device.

The method may alternatively be applied to the system shown in fig. 1, but is not limited thereto. The same descriptions as those of the method 600 in this embodiment have the same meaning, and are not repeated here. In this embodiment, the method includes at least part of the following.

Specific examples of the method 700 performed by the network device in this embodiment may be referred to the description related to the network device, such as the base station, in the method 600, and will not be repeated herein for brevity.
In this embodiment, the network device sends the maximum transmission power of the terminal device allowed by the network device, where the transmission power requirement is associated with the location information, so that the terminal device limits its own transmission power to be less than the maximum transmission power, thereby reducing interference caused by excessive transmission power of the terminal device to the network device.
In an application example of the embodiment of the present application, the problem of interference of an intra-terminal NR UE Tx signal (which may also be referred to as an NR uplink signal or simply as an NR Tx signal) to a UE SL Rx signal (which may also be referred to as an SL receive signal or simply as an SL Rx signal) when NR and SL operate in the same frequency band can be solved. See scheme 1 and/or scheme 2 below:
Scheme 1: the terminal reports the minimum frequency spectrum interval of the supported NR and SL working at the same time under the same frequency band.
Scheme 2: and the terminal reports the corresponding relation between the transmitting power of the NR UE Tx signal and the performance deterioration of the SL Rx signal.
In an application example of the embodiment of the present application, the problem of interference of the SL Tx signal of the UE to a network device, such as the gNB Rx signal (may also be referred to as a network receive signal) may also be solved. See scheme 3.
Scheme 3: the base station broadcasts the mode based on the Pmax of the position, pmax is the maximum transmitting power of the terminal allowed by the base station.
Under the condition that SL and NR are in the same frequency band, if the interference is avoided, the interference cannot work simultaneously in a time division mode, and the overall performance is reduced. In the embodiment of the application, the terminal reporting capability of the scheme 1 can realize simultaneous operation of SL and NR in the same frequency band, reduce interference and improve terminal performance. Scheme 2 reports corrupted information to maintain interference within a certain range through control of UE transmit power by the base station. Scheme 3 the base station limits the maximum transmitting power of the terminal based on Pmax of the geographic position, so that the interference to the base station end can be reduced, and the performance of the base station is improved.
Specific examples of the respective schemes are described below.
Example 1: interference of NR UE Tx signal inside UE to SL Rx signal
Fig. 13a and 13b are diagrams of interference of NR on SL inside the UE. As shown in fig. 13a, this is an interference situation when the SL timing of the terminal is aligned with the NR UE Rx signal, where the NR UE Tx signal is in the U1 range and the SL Rx signal is not interfering in the SL2 range, and the lengths of time of U1 and SL2 are equal to TA. As shown in fig. 13b, which is an interference case when the terminal SL Rx signal timing (which may be abbreviated as SL timing) is aligned with the NR UE Tx signal, two U slots overlap with two SL slots (i.e., UE NR Tx and UR SL Rx are simultaneously operated), and there is interference of the NR UE Tx signal to the SL Rx signal.
As shown in fig. 14a and 14b, when NR and SL operate in the same frequency band, in the terminal implementation architecture, a common radio frequency link or an independent radio frequency link may be used.
For the common radio frequency link architecture, there is no inter-link isolation between NR and SL, so serious interference can be brought under the condition of simultaneous operation. For this case, a time division mode (rotation) is often used to avoid interference, but the performance is affected.
Therefore, more often, NR and SL are operated simultaneously, and the terminal adopts an independent rf architecture of NR and SL to increase isolation between the NR UE Tx signal and the SL Rx signal and reduce interference, as shown in fig. 14 b.
The magnitude of the interference depends on two factors, the transmit power strength of the NR UE Tx signal, the isolation between the NR UE Tx signal and the SL Rx signal. The magnitude of the isolation (as shown in fig. 15) depends on the distance between the operating spectrum of the NR UE Tx signal and the spectrum of the SL Rx signal, the out-of-band leakage strength of the NR UE Tx signal spectrum, and the suppression degree of the out-of-band leakage of the SL Rx signal to the NR UE Tx signal. These factors are generally highly relevant to the implementation of the UE. The smaller the NR out-of-band leakage, the greater the suppression of the SL Rx signal to the NR UE Tx signal out-of-band leakage, the less the interference at the same spectrum spacing. For the same UE, the larger the spectral spacing between the NR UE Tx signal spectrum and the SL Rx signal spectrum, the less interference.
Based on the above analysis, to solve the interference of NR UE Tx signal to SL Rx signal when NR and SL are operating in the same frequency band, it can be performed by:
scheme one: the terminal reports the minimum spectrum interval gap_min between the NR UE Tx signal and the SL Rx signal required by the NR and the SL working at the same frequency band.
This minimum spectral interval may correspond to the minimum spectral interval at which the NR UE Tx signal maximum power is transmitted without causing interference to the SL Rx signal, or to the minimum spectral interval at which the interference received by the SL Rx signal at the NR UE Tx signal maximum power is transmitted does not exceed XdB.
When the spectrum interval between the NR UE Tx signal and the UE SL Rx signal is smaller than the minimum spectrum interval capability gap_min, the terminal SL Rx will be interfered with stronger, and the following processing manner may be further adopted:
mode 1, where the terminal NR UE Tx signal and the UE SL Rx signal are not performed simultaneously, i.e. in TDD mode
Mode 2, terminal NR UE Tx signal and UE SL Rx signal are performed simultaneously, but the UE SL Rx signal is allowed to take a certain sensitivity degradation. The degradation value of the sensitivity degradation may be predefined by a standard or may be a capability indication information reported by the terminal.
And after receiving the minimum spectrum interval capability gap_min, the base station refers to the gap_min value to schedule the use of spectrums of NR UE Tx signals and SL Rx signals.
When the actually scheduled spectrum interval is smaller than gap_min:
the base station may optionally perform the processing in the manner 1 described above. In this case, the base station needs to configure the UE with a rotation time template (TDD pattern) of NR UE Tx signal (abbreviated as NR Tx) and SL UE Rx signal (abbreviated as SL Rx), for example, as follows:
NR Tx SL Rx NR Tx SL Rx NR Tx SL Rx NR Tx SL Rx NR Tx SL Rx
the base station may also perform the processing in the above-described manner 2. In this case, the base station does not configure the alternate on-time template of the NR UE Tx signal and the UE SL Rx signal, but allows a certain sensitivity degradation of the UE SL Rx signal of the UE.
Scheme II: when the sensitivity of the UE SL Rx signal is deteriorated by XdB under the condition that the frequency spectrum positions of the NR UE Tx signal and the UE SL Rx signal are fixed, the terminal reports the maximum power capability Px that the terminal NR UE Tx signal can transmit. Wherein the sensitivity degradation XdB can be 0 or a value larger than 0, the value can be a predefined value (only Px is required to be reported at the moment) or a value reported by a terminal combination (XdB, px)
After receiving the maximum power capability Px which can be transmitted and the sensitivity worsened by the NR UE Tx signal reported by the terminal, the base station performs scheduling by referring to the maximum power capability. When the terminal transmission power exceeds Px and the sensitivity degradation X is greater than a predetermined value x_limit, the UE is allowed to disconnect the NR connection or disconnect the SL connection.
In this example, two schemes are given to circumvent interference of the NR UE Tx signal in the terminal to the SL Rx signal. In the first scheme, the terminal can report the minimum spectrum interval Gap to prompt the base station to avoid interference by adopting a larger spectrum interval as much as possible when scheduling carrier spectrum. In the second scheme, the terminal informs the network of the scheduling limitation of the NR transmitting power, that is, the relation between the NR UE Tx signal transmitting power and the SL Rx signal sensitivity deterioration, under the condition that the base station has difficulty in coordinating the spectrum, so that the network can schedule the transmitting power of the NR UE Tx signal without causing excessive SL Rx signal performance loss.
By the scheme, the interference between the NR UE Tx signal and the SL Rx signal in the terminal can be transparentized, and the interference in the terminal can be reduced through the base station.
The above scheme may belong to an optional feature for the base station.
Example 2: interference of UE SL Tx signal to NR gNB Rx signal
Fig. 16 is a schematic diagram of UE SL Tx signal interference gNB Rx signal. As shown in fig. 16, terminal SL transmissions will also interfere with the base station's uplink reception. Due to propagation delay between the terminal and the gNB, it results in: in the scenario of fig. 17a, the SL and SL1 Tx signals will interfere with the reception of U2 and U slots of gNB; in the scenario of fig. 17b the SL Tx signal will interfere with the reception of the U-slots of the gNB.
In the above scenario, the transmit power of SL may be limited to account for interference. In the related art, the SL transmit power control is open loop power control, that is, the SL transmit power is calculated based on preconfigured parameters (e.g., target power, propagation loss weighting). Wherein the propagation loss is a propagation loss between SL terminals related to the inter-SL terminal distance and not related to the distance between the terminal and the base station. This also results in terminals still transmitting relatively large power in the close proximity of the base station, causing interference of the UE SL Tx signal to the gNB Rx signal.
The power control mechanism of the present example may limit the SL power. For this reason, the limitation of the transmission power of the SL UE relatively close to the base station needs to be considered to reduce the reception interference to the gNB, as shown in fig. 18, which is a schematic diagram of the interference of the UE SL Tx in different areas to the base station.
In particular, a Pmax configuration based on geographic location (Pmax only works in partial locations) scheme can be adopted as follows:
pmax is typically used to define the maximum transmit power of the UEs within the cell, and the transmit power for all UEs within the cell after configuring the parameters in a single cell scenario is limited. This does not actually meet the above requirement, i.e. the goal is that Pmax will only work if the SL UE is at a relatively close distance from the base station. Based on this, the specific implementation is as follows:
mode 1 Pmax broadcast based on grid area
As shown in fig. 19, the cells are divided into a plurality of grid areas by geographic location, and information of the grid areas may be predefined. The terminal and the base station can clearly acquire their own positions, for example, in fig. 19, the base station is located in the grid 5.
The base station configures different Pmax values according to different grid areas where the terminal is located. For example, in fig. 19, a dark region (labeled 1 to 9) closer to the base station is configured with a Pmax1 to limit the transmit power of the UE to a lower power value. The light area (identified as 10 to 25) is configured with another Pmax2 to limit UE transmit power to another power value. The white area (identified as 26 to 49) remote from the base station, where the interference of the terminal SL transmissions to the base station is not significant, is not required to limit the transmission power of the terminal.
In a specific signaling design, pmax may correspond to the identity of the grid region, e.g., { Pmax1, grid 1/2/3/4/5/6/7/8/9}, { Pmax2, grid 10-25}, for example
Therefore, when the terminal enters the white area, SL transmission can be performed at a regular power. After the terminal enters the light area, the SL needs to control the transmit power according to Pmax 1. When the terminal enters a dark region, the SL needs to control the transmit power according to Pmax 2.
Mode 2 Pmax broadcast based on geographic location
In this manner, the transmission power may be limited based on the distance, in a manner similar to that of the manner 1, but without dividing the mesh region. The specific modes can include: the base station can carry the following information at the same time when Pmax broadcasting:
(1) Base station latitude and longitude position information, because the base station position information is unchanged, the information can be broadcast separately to save signaling overhead, or can be broadcast together with Pmax.
(2) Distance requirements.
(2-1) the distance requirement may be predefined without broadcasting.
For example, the Distance between the cell and the base station is divided into three areas of < Distance1, distance1 to Distance2, > Distance2, and three Pmax values { Pmax1, pmax2, pmax3} are broadcast. Where Pmax1 corresponds to the region of < Distance1, pmax2 corresponds to the region of Distance1 to Distance2, pmax3 corresponds to the region of > Distance 2.
(2-2) the distance requirement may also be broadcast by the base station as needed to define the range of use for different Pmax.
Such as { Pmax1, distance1}, { Pmax2, distance2} … (assuming Distance1< Distance2< …).
After acquiring the longitude and latitude position information of the base station, the terminal can acquire the actual distance from the base station, namely the distance UE, by combining the longitude and latitude information of the terminal, and limit the transmitting power based on the Pmax and the distance requirement broadcasted by the base station. For example:
when Distance is less than or equal to Distance1, the maximum transmitting power of the SL signal of the UE does not exceed Pmax1;
when Distance1< Distance UE +.distance 2, the maximum transmit power of the UE SL signal should not exceed Pmax2.
In this example, through the Pmax broadcast based on the location, the problem of interference on the gNB Rx signal caused by the SL terminal being located at the cell center and transmitting high power can be effectively solved.
Through the technical scheme, the interference of NR Tx in the UE to the UE SL Rx in the same frequency band of NR and SL can be solved, and the interference of the UE SL Tx to gNB Rx can be also solved.
