Description

Power adjustment method and device and communication equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a power adjustment method and apparatus, and a communication device.

Background

There are two resource allocation methods for a New Radio (NR) Sidelink (SL), one is based on base station scheduling, and the other is based on terminal (UE) autonomous resource selection. For the resource allocation mode of base station scheduling, sidelink resources used by the UE for data transmission are determined by the base station and are notified to a sending end (TX) UE through a downlink signaling; for the resource allocation mode selected by the UE autonomously, the UE selects available transmission resources in a (pre) configured resource pool, the UE performs channel monitoring before resource selection, selects a resource set with less interference according to a channel monitoring result, and then randomly selects resources for transmission from the resource set.

In autonomous resource selection mode, a resource pre-projection mechanism is supported. A UE with low priority traffic triggers resource reselection when the resource that the UE has reserved overlaps (partially overlaps) the resource reserved by other UEs with higher priority traffic and the measured value of the SL-Reference Signal Receiving Power (RSRP) on the relevant resource is greater than a relevant SL-RSRP threshold value.

In the existing preemption mechanism of the Internet of vehicles, whether the preemption is related to the priority of the service transmission of the terminal and the value of the measured RSRP can be preempted. And the terminal with low priority can trigger resource reselection after the resource is robbed. However, the terminal may have the situation that continuous resources are robbed, thereby causing the problems of low resource selection efficiency of the terminal, large service delay and the like. Meanwhile, the terminal frequently performs resource selection and/or reselection, and sends a signaling for resource selection and/or reselection, thereby increasing interference in the system.

Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 may also be referred to as a terminal Device or a terminal (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network-side device 12 may be a Base Station or a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), or a location server (e.g., an E-SMLC or an lmf (location Manager function)), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary, and it should be noted that, in the embodiment of the present invention, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication link in the wireless communication system may include an Uplink for carrying Uplink (UL) transmission (e.g., from the terminal 11 to the network side device 12), or a Downlink for carrying Downlink (DL) transmission (e.g., from the network side device 12 to the terminal 11), and a sidelink (SL, or vice link, side link, etc.) for carrying transmission between the terminal 11 and other terminals 11. The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

A Long Term Evolution (LTE) system supports SL, and is used for directly transmitting data between terminals (UEs) without using a network device.

The design of the LTE sidelink is suitable for specific public safety affairs (emergency communication in disaster places such as fire places or earthquakes), vehicle to internet (V2X) communication and the like. The internet of vehicles communication includes various services, such as basic security type communication, advanced (automated) driving, formation, sensor expansion, and the like. Since LTE sidelink only supports broadcast communication, it is mainly used for basic security communication, and other advanced V2X services with strict Quality of Service (QoS) requirements in terms of delay, reliability, etc. will be supported by New Radio (NR) sidelink.

The UE transmits Sidelink Control Information (SCI) through a Physical Sidelink Control Channel (PSCCH), and schedules transmission of a Physical Sidelink Shared Channel (PSCCH) to transmit data. After receiving the sidelink control information, the receiving end UE demodulates the sidelink control information, and determines the size of the transmission block, the modulation coding mode, the allocated resources and the like according to the demodulated sidelink control information. And the receiving end receives data on the corresponding time frequency resources according to the information and demodulates the data. Wherein the SCI may be carried on PSCCH and/or PSCCH. The terminal can be a mobile phone, a vehicle, a roadside unit, an infrastructure and the like.

There are two New Radio (NR) SL resource allocation manners, one is based on base station scheduling (mode 1 resource allocation in NR V2X, mode 3 resource allocation in LTE V2X, and mode 1 resource allocation in LTE 2D), and the other is based on UE autonomous resource selection (mode 2 resource allocation in NR V2X, mode 4 resource allocation in LTE V2X, and mode2 resource allocation in LTE D2D). For the resource allocation mode of base station scheduling, sidelink resources used by the UE for data transmission are determined by the base station and are notified to a sending end (TX) UE through a downlink signaling; for the resource allocation mode selected by the UE autonomously, the UE selects available transmission resources in a (pre) configured resource pool, the UE performs channel monitoring before resource selection, selects a resource set with less interference according to a channel monitoring result, and then randomly selects resources for transmission from the resource set. In addition, the rule for the UE to perform resource selection (including the condition for the UE to perform resource selection or resource reselection) is strictly defined by the standard.

In addition, at the time of SL transmission (PSCCH and/or PSCCH transmission), the UE may reserve transmission resources for the next and/or multiple transmissions (new or retransmission). The UE may reserve resources for the next Transport Block (TB) transmission through a "periodic reservation field" in the control information (SCI), and may reserve retransmission resources for the current TB transmission through a "time domain resource indication field" in the control information (SCI).

The basic principle of autonomous resource selection is as follows:

the UE analyzes the SCI and measures Reference Signal Receiving Power (RSRP) in each Transmission Time Interval (TTI), to obtain information such as resource reservation and RSRP measurement values, and according to the information such as resource reservation and RSRP measurement values obtained within the length of a detection window, the UE performs resource exclusion and reservation on resources within a resource selection window. The basic steps of resource exclusion and reservation are as follows:

step 1: and the terminal detects the resources and obtains the candidate resources in the resource selection window.

Excluding the slot (slot) resource of the UE for sending data;

excluding slot (slot) resources which are reserved by other UE and related to SL-RSRP measurement values which are greater than a SL-RSRP threshold in a resource selection window based on information such as resource reservation and RSRP measurement values obtained in the sending window;

if the candidate resources identified in the resource selection window are less than X% of the total number of resources in the resource selection window, the SL-RSRP threshold is +3dB, so that more resources can become candidate resources.

Step 2: and randomly selecting resources from the identified candidate resources in the resource selection window, and reserving the resources.

Reservation of retransmission resources may be supported, and reservation of Semi-Persistent Scheduling (SPS) resources, that is, reservation of periodic resources may also be supported.

Fig. 2 is a schematic diagram illustrating autonomous resource selection performed by a terminal, where n in the diagram is a trigger time of resource selection and/or reselection; n + T1 is the starting point of a resource selection window (selection window) (the duration of T1 is the self-processing duration required by the UE to select the resource); n + T2 is the end point of the resource selection window; n + T0 is the starting point of the resource sending window. Wherein, Resource (re-) selection trigger is used to trigger Resource selection or reselection, Candidate Resource based sensing is used as Candidate Resource, and SPS reservation is used as semi-static reserved Resource.

In autonomous resource selection mode, a resource pre-projection mechanism is supported. A UE with low priority traffic triggers a resource reselection when the resources already reserved by one UE overlap (partially overlap) with the resources reserved by other UEs with higher priority traffic and the measured SL-RSRP value of these UEs on the relevant resources is greater than a certain relevant SL-RSRP threshold value (associated SL-RSRP threshold).

In the existing preemption mechanism of the Internet of vehicles, whether the preemption is related to the priority of the service transmission of the terminal and the value of the measured RSRP can be preempted. If the resources of terminal 1 are preempted by terminal 2 (the priority of terminal 1 is lower than that of terminal 2, and terminal 1 measures that the SL-RSRP of terminal 2 is higher than the defined value of SL-RSRPthreshold), terminal 1 performs a resource reselection in order to send data. Since the priority of the terminal 1 is lower, after the resource reselection is performed, it is still possible that the reselected resource will be preempted by other terminals. This may result in the terminal 1 performing a number of unnecessary resource selections and/or reselections, consuming energy from the terminal 1. Since the terminal 1 will send the reservation signaling after performing resource selection and/or reselection, multiple resource selections and/or reselections cause more complex and serious interference in the system.

An embodiment of the present invention provides a power adjustment method, applied to a terminal, as shown in fig. 3, including:

step 101: and if the terminal occupies the resources or the resources of the terminal are occupied, adjusting the sending power.

In this embodiment, if a terminal occupies resources or resources of the terminal are occupied, the terminal adjusts the transmission power, and changes the relationship between the RSRP value and the RSRP threshold of the terminal detected by other terminals by adjusting the transmission power of the terminal in the preemption mechanism, so that frequent resource selection and/or resource reselection by the terminal can be avoided when the terminal that occupies resources selects resources, the situation that continuous resources are occupied by the terminal can be reduced, interference to other terminals in the system is reduced, and the performance of the terminal in the communication system is ensured.

If the service priority of a terminal is lower than the service priorities of other terminals, and the measured RSRP is higher than the threshold, it can be determined that the resource of the terminal is preempted, and the terminal is the terminal with the preempted resource, so that the resource selection or resource reselection of the terminal can be triggered, and if the resource selection and/or reselection cannot be performed in time, the terminal can still send information on the preempted resource. In addition, the information is obtained by measuring the RSRP, so that whether the resources of other terminals are occupied or not can be obtained, and if the resources of other terminals are occupied, the terminal is the terminal which occupies the resources.

The adjustment value of the transmission power may be greater than 0, may also be less than 0, and may also be equal to 0, and when the adjustment value of the transmission power is greater than 0, it is that the terminal raises the transmission power; when the adjustment value of the transmission power is smaller than 0, the terminal decreases the transmission power. Or the adjusted value of the transmission power may be greater than or equal to 0, and the terminal may increase or decrease the transmission power according to the adjusted value of the transmission power.

In the exemplary embodiment of the present invention, if the resource of the terminal is preempted, the adjusting the transmission power includes any one of:

when the terminal with the preempted resources selects and/or reselects the resources, the power of a sending signal and/or a channel is adjusted;

the terminal preempting the resource reduces the transmission power when transmitting data on the preempted resource.

If the terminal with the preempted resource selects and/or reselects the resource, the power of a sending signal and/or a channel can be increased, so that the RSRP measured by other terminals is higher than the RSRP threshold, the resource selected and/or reselected by the terminal cannot be preempted, and frequent resource selection and/or reselection is avoided. Of course, if the terminal with the preempted resource performs resource selection and/or reselection, the power of the transmission signal and/or channel can be reduced.

Optionally, the channel includes at least one of:

a Physical Sidelink Control Channel (PSCCH);

a physical side link shared channel PSSCH;

a physical sidelink feedback channel PSFCH;

and/or the presence of a gas in the gas,

the signal comprises at least one of:

demodulation reference signal (DMRS), including PSCCH DMRS and PSSCH DMRS;

a channel state information reference signal (CSI-RS);

a Phase Tracking Reference Signal (PTRS).

Wherein the signals and/or channels may be predefined or preconfigured or configured. When the signal and/or channel is configured, the signal and/or channel may be explicitly configured or implicitly configured.

In a specific example, if the configuration is such that the power of the PSCCH, and the power of the DMRS can be changed (e.g., increased), further, the specific change of which power can be an explicit and/or implicit configuration of the network side device (e.g., a base station).

Optionally, the signal and/or channel is associated with configuration information of a measurement signal of reference signal received power, RSRP, and the method further includes:

and acquiring configuration information of the measurement signal of the RSRP.

If the RSRP is measured according to PSCCH DMRS, the transmit power of the PSCCH is increased, and similarly, if the RSRP is measured according to PSSCH DMRS, the transmit power of the PSCCH is increased. It should be noted that if the transmission power is increased by the control information, data, etc. carried on PSCCH and/or PSCCH, the power of PSCCH DMRS and/or PSSCH DMRS is changed accordingly, which may affect the measurement results of other terminals in the system

Optionally, the method further comprises any one of:

a terminal with a preempted resource sends first indication information to indicate whether measurement of RSRP is effective or not;

the terminal with the preempted resource sends first indication information to indicate whether to measure the RSRP of the resource carried by the second indication information;

and the terminal with the preempted resource sends the first indication information to indicate whether to measure the RSRP of the resource scheduled by the second indication information.

The first indication information and the second indication information may be SCI or PSCCH, and the first indication information and the second indication information may be the same SCI or PSCCH of the same slot or different SCIs or PSCCH of different slots.

In another specific example, if the configuration is such that the power of the PSCCH and the power of the PSCCH can be changed (e.g., increased), further, the specific change of which power can be an explicit and/or implicit configuration of the network side device (such as the base station). If the power of PSCCH DMRS and PSSCH DMRS is not changed, only the transmission power of the PSCCH and/or PSSCH is changed, and the measurement results of other terminals in the system are not influenced.

In a specific example, the adjusting the power when transmitting the signal and/or the channel includes:

and adjusting the power when the signal and/or the channel is transmitted by taking a transmission power reference value as a reference, wherein the transmission power reference value adopts any one of the following items:

the scheduled transmission power of the terminal with the preempted resource on the preempted resource;

the terminal of the preempted resource sends the power of second indication information, and the second indication information is the indication information for reserving the preempted resource;

the terminal with the preempted resource transmits the control information or data before transmitting the control information or data for resource selection and/or reselection by using the transmission power used in the last transmission of the control information or data.

In the exemplary embodiment of the present invention, the terminal that preempts the resource still transmits data on the preempted resource, and the transmission power of the preempted terminal is decreased. One scenario applicable here is that a terminal with a preempted resource finds that the resource is preempted, but is not in time to perform resource reselection, so that the terminal with the preempted resource still uses the preempted resource to transmit data, and at this time, the terminal with the preempted resource reduces transmission power to reduce interference to other terminals in the system.

In a specific example, adjusting the transmit power comprises:

when the value of the second parameter is smaller than the corresponding threshold value, the adjustment value of the transmission power is 0 or the adjustment of the transmission power is not performed,

and/or the presence of a gas in the gas,

when the value of the second parameter is greater than or equal to the corresponding threshold value, the adjustment value of the transmission power is not 0;

wherein the second parameter comprises at least one of:

the priority of the service to be sent by the terminal with the seized resources;

the difference value between the priority of the service to be sent by the terminal with the seized resource and the priority of the service to be sent by the terminal with the seized resource;

the number of times of terminal resource selection and/or reselection of the preempted resources;

the terminal with the preempted resource receives the negative acknowledgement NACK and/or the discontinuous DTX receiving times;

the remaining time of the service to be sent of the terminal with the seized resource;

the data volume to be transmitted of the terminal with the preempted resources;

a channel occupancy (CR) in the resource pool;

channel Busy Ratio (CBR) in the resource pool.

Wherein the threshold value is predefined or preconfigured or configured.

Wherein the adjustment value of the transmission power may be predefined or preconfigured or configured.

In a specific example, the adjustment value of the transmission power is related to at least one of the following first parameters:

the terminal with the preempted resource receives the times of NACK and/or DTX;

the data volume to be transmitted of the terminal with the preempted resources;

channel occupancy in the resource pool;

channel busy rate in the resource pool;

the service type (i.e. unicast, multicast, broadcast) of the terminal with the preempted resource;

the service type of the terminal occupying the resource (i.e. unicast, multicast, broadcast).

Optionally, a first mapping relationship between the adjustment value of the transmission power and the first parameter is predefined or preconfigured or configured.

Optionally, the first mapping relationship is predefined or preconfigured or configured for at least one of:

each resource pool;

each CBR range;

each terminal;

each process;

each logical channel;

each logical channel group.

Preferably, the first mapping relation may be configured for each resource pool.

In a specific example, the pre-assignment mechanism is predefined as enabling, and the terminal with the preempted resource performs power adjustment according to the difference between the priority of the terminal with the preempted resource and the priority of the terminal with the preempted resource when performing resource selection and/or reselection. (this may be an implicit configuration, associated with the enablement of the pre-indication mechanism).

In the resource pool, a mapping relation between a difference value of a priority of a service to be sent of a terminal with preempted resources and a priority of a service to be sent of the terminal with preempted resources and an adjustment value of sending power of the terminal with preempted resources is preconfigured as follows:

if the priority difference is 1, the power is increased by a1 dB;

the priority difference is 2, the power is increased by a2 dB;

the priority difference is 3, the power is increased by a3 dB;

the priority difference is 4, the power is increased by a4 dB;

the priority difference is 5, the power is increased by a5 dB;

the priority difference is 6, the power is increased by a6 dB;

the difference in priority is 7, the power is increased by a7 dB.

If the pre-assignment mechanism is enabled, when the priority of the service to be sent by the terminal with the preempted resources is lower than that of the service to be sent by the terminal with the preempted resources, and the value of the RSRP measured by the terminal with the preempted resources is higher than the RSRP threshold value, the terminal with the preempted resources performs resource selection and/or reselection. And the terminal with the preempted resource acquires the adjustment value of the sending power according to the difference of the priority and the defined mapping relation. If the priority difference is 4, the transmission power of the terminal with the preempted resource is increased by a4 dB according to the defined mapping relation. Therefore, when the terminal that has preempted the resource transmits the resource reservation information (control information) of the reselection resource or transmits data on the reselection resource, the power of the terminal that has preempted the resource is increased by a4 dB from the power of the last transmission information as a candidate value of the transmission power.

In the exemplary embodiment of the present invention, if the terminal occupies the resource, adjusting the transmission power includes:

and the terminal for preempting the resource increases the transmission power when transmitting data according to the adjustment value of the transmission power on the resource preemption.

Wherein the adjustment value of the transmission power may be predefined or preconfigured or configured, and may further be related to at least one third parameter of:

preempting the priority of the service to be sent of the terminal of the resource;

the terminal occupying the resource waits for the remaining time of the service to be sent;

the method comprises the steps that the data volume to be transmitted of a terminal preempting resources;

channel occupancy in the resource pool;

channel busy rate in the resource pool;

the service type of the terminal with the seized resource;

and the service type of the terminal occupying the resources.

Optionally, a second mapping relationship between the adjustment value of the transmission power and the third parameter is predefined or preconfigured or configured.

Optionally, the second mapping relationship is predefined or preconfigured or configured for at least one of:

each resource pool;

each CBR range;

each terminal;

each process;

each logical channel;

each logical channel group.

After the terminal adjusts the transmission power, the transmission power after the terminal adjustment adopts the minimum value of the following values:

obtaining a second candidate sending power according to the side link path loss and/or obtaining a third candidate sending power according to the downlink path loss;

if the resources of the terminal are preempted, adjusting the sending power of the terminal based on the preempted power control parameters when sending data on the preempted resources;

if the terminal occupies the resources, adjusting the sending power of the terminal based on the occupied power control parameter;

if the resources of the terminal are preempted, on the selected resources, the reselected resources and/or the indication information indicating the reselected resources, the transmission power of the terminal is adjusted based on the preempted power control parameters.

Optionally, on the selected resource, the reselected resource, and/or the indication information indicating the reselected resource, adjusting the transmission power of the terminal based on the preempted power control parameter includes:

if the resource pool is configured to measure RSRP based on a PSCCH demodulation reference signal (DMRS), adjusting the transmission power of the terminal when the indication information indicating the reselection resources is transmitted;

if the resource pool is configured to measure RSRP based on psch demodulation reference signals, the transmit power of the terminal is adjusted on the selected and/or reselected resource.
