Detailed Description
As noted in the background, the prior art does not consider the problem of how to allocate the transmission power between the channels when the UE simultaneously transmits multiple channel information on the direct link.
The embodiment of the invention provides a method for distributing transmitting power, which comprises the following steps: when control information is sent on a plurality of channels of a direct connection link, determining the arrangement sequence of the plurality of channels; according to the arrangement sequence, the transmitting power of each channel is distributed in sequence; wherein the control information comprises one or more of: HARQ feedback information, channel state information, scheduling request information. Through the technical scheme provided by the embodiment of the invention, when the UE needs to send the control information on a plurality of channels, the transmitting power can be sequentially distributed based on the determined channel arrangement sequence so as to send a plurality of control information on the direct link at the same time, and a feasible scheme is provided for distributing the transmitting power of each channel to the UE with constant total transmitting power.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The term "simultaneous transmission" as used herein refers to overlapping or partial overlapping in time between the time-frequency resources of the bearer channels, or overlapping or partial overlapping in time and frequency between the time-frequency resources of the bearer channels.
It should be noted that "Priority of a Physical direct link shared Channel (psch)" appearing herein may be determined by a Priority of a near field communication data Packet (ProSe Per-Packet Priority, PPPP) corresponding to transmission carried by the psch, where a lower value of the PPPP means a higher Priority of the corresponding transmission, and the PPPP may be indicated by SCI (system Information Control, direct link Control for short) or higher layer signaling. The PPPP value may be related to at least one of a QoS priority (priority), a latency (latency), a reliability (reliability), and a minimum required communication distance (minimum required communication range).
Fig. 1 is a flowchart illustrating a method for allocating transmission power according to an embodiment of the present invention. The allocation method may be performed by a terminal, for example by an NR V2X UE. Specifically, the allocation method may include the steps of:
step S101, when control information is sent on a plurality of channels of a direct connection link, determining the arrangement sequence of the plurality of channels;
and step S102, sequentially distributing the transmitting power of each channel according to the arrangement sequence.
Wherein the control information may include one or more of: hybrid automatic Repeat reQuest (HARQ) feedback information, Channel State Information (CSI), and Scheduling ReQuest (SR) information.
The HARQ feedback information includes ACKnowledgement/negative ACKnowledgement (ACK/NACK).
The CSI may include one or more of: channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), Rank Indicator (RI), Reference Signal Receiving Power (RSRP), Received Signal Strength Indicator (RSSI), Signal to Noise Interference Ratio (SINR), CSI-Resource Indicator (CRI), and Synchronization Signal Block Resource Indicator (SSBRI). Wherein the reference signal received power may be a physical layer RSRP (i.e., L1-RSRP) and the received signal strength indication may be a physical layer RSSI (i.e., L1-RSSI).
The plurality of channels may be a Plurality of (PSFCH) channels. Alternatively, the plurality of channels may be a number of PSFCH channels and a number of passable PSSCH channels. Alternatively, the plurality of channels may be a plurality of PSFCHs, a plurality of PSSCHs, and a physical direct link Control CHannel (PSCCH). Still alternatively, the multiple channels may be a plurality of PSFCHs, a plurality of Physical link Discovery channels (PSDCHs), and the like.
In step S101, if the UE needs to transmit multiple pieces of control information on multiple channels of the direct link at the same time, in order to determine the transmission power of each channel, an arrangement order of the multiple channels may be determined, so as to allocate the transmission power of each channel to the UE with a constant total transmission power.
As a specific embodiment, if the control information is the same type of control information and the multiple channels are all PSFCHs, the ranking order of the PSFCHs may be determined according to the priorities of the PSSCHs associated with the PSFCHs. For example, when there are multiple PSFCHs, one of which has the highest priority for the pschs associated with it, its transmit power is allocated preferentially in the power allocation. For the remaining PSFCHs, the same may be done, with their transmit powers allocated in order of priority from high to low.
The information related to the priority of the PSCCH may be carried by the PSCCH, which schedules the PSCCH. The priority related information may be carried in a display mode, or may implicitly indicate, for example, a latency requirement (latency requirement) of data transmitted through the pschs, and implicitly indicate a priority of each psch.
Wherein, if the priorities of the PSSCHs corresponding to a plurality of PSFCHs are the same, the UE implementation is used for deciding which PSFCHs are preferentially allocated to transmit power.
As a non-limiting example, when the priorities of the PSSCHs associated with the respective PSFCHs are the same, the UE may randomly generate the ranking order of the respective PSFCHs and determine the ranking order of the respective PSFCHs. Alternatively, the UE may determine the permutation order of the PSFCHs according to the resource index value of the resource occupied by each PSFCH. In a specific implementation, the resource index values may be arranged in a descending order, or may be arranged in a descending order.
As a further non-limiting example, if the control information is the same type of control information and the plurality of channels are all PSFCHs, the ranking order of the respective PSFCHs may be determined according to communication ranges (communication ranges) over which the respective PSFCHs transmit data.
In a specific implementation, the ranking order of the PSFCHs may be determined according to the descending order of the communication distances or the descending order of the communication distances, and the transmission power of each PSFCH may be allocated according to the ranking order.
Wherein the communication distance may be a specific communication distance. In practical applications, the communication distance may also be represented according to the value of RSRP or RSSI of the reference signal. The Reference Signal may be a demodulation Reference Signal (De-Modulation Reference Signal, DMRS for short) of the PSFCH, or a DMRS for a PSSCH associated with the PSFCH, or a DMRS for scheduling a PSCCH corresponding to the PSSCH associated with the PSFCH, or an associated Channel State indication Reference Signal (CSI-RS) of the direct link, or an associated Synchronization Signal and physical broadcast Channel Block (SSB) of the direct link.
As a variation, the communication distance may also be represented according to the value of RSRP or RSSI of the channel. The channel may be a PSFCH, or a PSSCH associated with the PSFCH, or a scheduled PSCCH corresponding to the PSSCH associated with the PSFCH. The higher the RSRP or RSSI value is, the closer the corresponding communication distance is, and otherwise, the longer the corresponding communication distance is.
Wherein, if there are a plurality of PSFCHs corresponding to the same communication distance, the UE is used for deciding which PSFCHs are preferentially allocated for transmission power.
As a non-limiting example, when the communication distances over which the respective PSFCHs transmit data are the same, the UE may randomly generate the permutation order of the respective PSFCHs. Alternatively, the UE may determine the permutation order of the PSFCHs according to the resource index value of the resource occupied by each PSFCH.
As another non-limiting example, if the control information is the same type of control information, and the multiple channels are all PSFCHs, the permutation order of the PSFCHs may be determined according to the data transmission manner of the PSSCH associated with each PSFCH, where the data transmission manner may be selected from unicast, multicast, and broadcast.
In a specific implementation, the UE may first determine the data transmission mode of the pschs associated with the respective PSFCHs. Then, the permutation order of the PSFCHs may be determined according to the data transmission manner.
For example, the data transmission manner only includes unicast and multicast, and in this case, the UE may order the PSFCHs associated with the PSSCH for transmitting data by using multicast before the PSFCHs associated with the PSSCH for transmitting data by using unicast, and order the PSFCHs associated with the PSSCH for transmitting data by using unicast after the PSFCHs associated with the PSSCH for transmitting data by using multicast, that is, preferentially allocate the transmission power of the PSFCHs associated with the PSSCH for transmitting data by using multicast. Otherwise, the UE may rank the pscch associated pscch for unicast data transmission before the pscch associated pscch for unicast data transmission, and rank the pscch associated pscch for multicast data transmission after the pscch associated pscch for unicast data transmission, that is, preferentially allocate the transmit power of the pscch associated pscch for unicast data transmission.
In a specific implementation, when the data transmission modes of the PSSCHs associated with the respective PSFCHs are the same, the UE may randomly generate the permutation order of the respective PSFCHs, and determine the permutation order of the respective PSFCHs. As a variation, the UE may also determine the permutation order of the PSFCHs according to the resource index value of the resource occupied by each PSFCH. The PSFCH may be ordered in the front with smaller resource index values of the resources occupied by the PSFCH, that is, the transmission power of the PSFCH with smaller resource index values is preferentially allocated; alternatively, the PSFCH may have the resource index values of the resources occupied by the PSFCH ordered in a larger order, i.e., the transmission power of the PSFCH with the smaller resource index value is preferentially allocated.
As another variation, the UE may also determine the permutation order of the PSFCHs according to the first symbol (symbol) or the first slot (slot) of the resource occupied by each PSFCH. In a specific implementation, the first symbol of the resource occupied by the PSFCH or the PSFCH preceding the first slot (i.e. temporally preceding) may be ordered in the front, i.e. the transmission power of the PSFCH preceding the first symbol or the first slot is preferentially allocated.
In a specific implementation, if there are multiple PSFCHs with the same first symbol or first timeslot, the time domain lengths of the PSFCHs may be compared, and the PSFCH with a longer time domain length is ordered first, i.e. the transmission power of the PSFCH with a longer time domain length is preferentially allocated. Alternatively, if there are multiple PSFCHs with the same first symbol or first slot, the time domain lengths of these PSFCHs may be compared, and the PSFCH with shorter time domain length is ordered first, i.e. the transmission power of the PSFCH with shorter time domain length is preferentially allocated.
In a specific implementation, if there are multiple PSFCHs with the same first symbol or first slot and the same time domain length, the UE may randomly select the ordering of the PFSCHs and sequentially allocate the transmission power of the PSFCHs according to the random ordering.
As another variation, the UE may also determine the arrangement order of each PSFCH according to a first symbol (symbol) or a first slot (slot) of a time-frequency resource occupied by the PSSCH associated with each PSFCH. The first symbol of the resource occupied by the pscch associated with the PSFCH or the PSFCH with the first slot in front may be ordered in front, i.e. the transmit power of the PSFCH with the first symbol of the associated PSSCH or the first slot in front is preferentially allocated. As another non-limiting example, if the control information is different control information and the plurality of channels are all PSFCHs, the UE may first determine an arrangement order of various control information, and then the UE may determine an arrangement order of various physical direct link feedback channels according to the arrangement order of various control information.
In a specific implementation, if there are multiple PSFCHs associated with the same PSSCH, the first symbol or the first slot of the occupied time-frequency resource may be compared with the time-domain lengths of the PSSCHs, and the PSSCHs with longer time-domain lengths are ordered in the front, that is, the transmission power of the first symbol or the first PSFCH with longer time-domain length associated with the PSSCH is preferentially allocated. Alternatively, if there are multiple pschs with the same first symbol or first slot, the time domain lengths of these pschs may be compared, and the pschs with shorter time domain lengths may be ordered first, i.e. the transmission power of the first symbol or first PSFCH with shorter time domain length associated with the pschs may be allocated preferentially.
In a specific implementation, if there are multiple PSFCHs associated with the same PSSCH, that is, if the first symbol or the first slot of the occupied time-frequency resource is the same, and the time-domain lengths of the PSSCHs are the same, the UE may randomly select the ordering of the PFSCHs, and sequentially allocate the transmission power of the PSFCHs according to the random ordering.
In particular implementations, the priority of various different control information may be predefined. As one non-limiting example, the control information includes SR information, HARQ feedback information, and CSI. The SR information, the HARQ feedback information, and the CSI may be predefined to be sequentially lower in priority. Alternatively, it may be predefined that the priorities of the HARQ feedback information, the SR information, and the CSI are sequentially lowered. Alternatively, it may be predefined that the HARQ feedback information, the priority of the CSI, and the SR information are sequentially reduced. Alternatively, it may be predefined that the SR information, the HARQ feedback information, and the CSI are sequentially lower in priority. Alternatively, it may be predefined that the priorities of the CSI, the HARQ feedback information, and the SR information are sequentially lowered. Alternatively, it may be predefined that the priorities of the CSI, the SR information, and the HARQ feedback information are sequentially lowered. Thereafter, the arrangement order of the various control information may be determined according to the predefined priorities of the various control information.
As another specific embodiment, the multiple channels are different types of channels, and at this time, the UE may first determine an order of arrangement of the different types of channels, and then determine an order of arrangement of the feedback channels of each physical direct link according to the order of arrangement of the different types of channels. Wherein the different types of channels may include at least two of: PSFCH, PSSCH, PSCCH, PSDCH.
In step S102, the UE may sequentially allocate the transmission power of each channel according to the permutation order of the plurality of channels.
Take the control information as HARQ feedback information as an example. In a specific implementation, if the PSFCH only supports transmission of HARQ feedback information, and there are multiple PSFCHs that need to transmit HARQ feedback information at the same time (e.g., the same timeslot), the rank order of each PSFCH may be determined according to the priority of the PSSCH corresponding to the PSFCH, and the transmission power of the PSFCH with a higher priority may be preferentially allocated.
In a specific implementation, it is assumed that there are M PSFCHs, where M is a positive integer greater than 1, where PSFCH1 is N1, associated PSSCH1, PSFCH2 is N2, associated PSSCH2, … …, PSFCHn is Nn, associated psschhn, N1, N2 …, Nn, N is a positive integer. N1+ N2+ … … + Nn ═ M. And the priorities of the PSSCH1, PSSCH2, … … and PSSCHn are sequentially lowered. At this time, the UE may preferentially allocate the transmit power of N1 PSFCHs 1, and then sequentially allocate the transmit power of the PSFCHs 2, … …, and PSFCHn. For each PSFCH1 or PSFCH2 or other PSFCHs, power allocation can be performed according to similar method schemes as follows, and is not expanded here.
In a specific implementation, it is assumed that there are two PSFCHs, with PSFCH1 associated with PSSCH1, PSFCH2 associated with PSSCH2, and PSSCH1 having a higher priority than PSSCH 2. At this time, the UE may preferentially allocate the transmit power of the PSFCH 1. Suppose PPSFCH1Indicating the transmit power of the psch 1, the transmit power of the channel psch 1 may be determined according to existing protocols and will not be described in detail here. The UE may then allocate transmit power for the PSFCH 2. Transmitted work P of PSFCH2PSFCH2Can be min { PCMAX–PPSFCH1,Ptypical}. Wherein, min { P }CMAX-PPSFCH1，PtypicalMeans to select PCMAX-PPSFCH1、PtypicalMinimum value of (1), PCMAXRepresenting the maximum transmission power, P, of the user equipmenttypicalRepresenting at least the transmit power associated with the number of frequency domain resources of the PSFCH 1. Specifically, PCMAXIt can be expressed that the maximum transmission power of the user equipment on the component carrier (component carrier) is.

Taking the control information as HARQ feedback information as an example. In a specific implementation, if the PSFCH only supports transmission of HARQ feedback information, and there are multiple PSFCHs that need to transmit HARQ feedback information at the same time (e.g., the same timeslot), the rank order of the PSFCHs may be determined according to the communication distances for transmitting data by the PSFCHs, and the transmission power of the PSFCH with a higher priority may be preferentially allocated. It should be noted that the communication distance may refer to an actual communication distance, and may also refer to a communication distance represented by RSSI or RSRP, and specific contents may refer to the foregoing, and are not repeated here.

In a specific implementation, if there are multiple PSFCHs that need to be transmitted simultaneously, the UE may preferentially allocate the transmission power of the PSFCH ordered before according to the data transmission mode corresponding to the PSSCH associated with the PSFCH.
For example, assume that there are two PSFCHs, where PSFCH1 is associated with PSSCH1,the PSFCH2 associates with PSSCH2, and the PSSCH1 employs multicast transmission and the PSSCH2 employs unicast transmission. The UE may preferentially allocate transmit power of the PSFCH1 when the priority of multicast is predefined to be higher than the priority of unicast. Suppose PPSFCH1Indicating the transmit power of the PSFCH1, the transmit power of the channel PSFCH1 may be determined according to existing protocols and will not be described in detail here. The UE may then allocate transmit power for the PSFCH 2. Transmitted work P of PSFCH2PSFCH2Can be min { PCMAX-PPSFCH1,Ptypical}.

And PtypicalMay include at least a frequency domain resource amount (e.g., a resource block amount and/or a subchannel amount) of the PSFCH1, and/or a path loss of a direct link of the UE.
For example, assume that there are two PSFCHs, with PSFCH1 associated with PSSCH1, PSFCH2 associated with PSSCH2, and PSSCH1 using unicast transmission and PSSCH2 using multicast transmission. The UE may preferentially allocate transmit power of the PSFCH1 when the priority of multicast is predefined to be lower than the priority of unicast. Suppose PPSFCH1Indicating the transmit power of the PSFCH1, the transmit power of the channel PSFCH1 may be determined according to existing protocols and will not be described in detail here.

In a specific implementation, when the control information is different control information and the plurality of channels are all PSFCHs, after the UE determines the permutation order of the PSFCHs, the UE may sequentially allocate transmission power to the PSFCHs.
As a non-limiting example, if there are multiple PSFCHs that need to be transmitted simultaneously and the priority of the PSFCH carrying CSI is lower than that of the PSFCH carrying HARQ feedback information, the UE may preferentially allocate power to the PSFCH carrying HARQ feedback information. Those skilled in the art understand that, if there are multiple PSFCHs carrying CSI or multiple PSFCHs carrying HARQ feedback information, the foregoing embodiments may be adopted, and details are not repeated here.
For example, assuming that there are two PSFCHs, where PSFCH1 is associated with PSSCH1, PSFCH2 is associated with PSSCH2, and PSSCH1 carries HARQ feedback information, PSSCH2 carries CSI, and the priority of HARQ feedback information is higher than the priority of CSI, the transmit power of PSFCH1 may be allocated preferentially. Suppose PPSFCH1Indicating the transmit power of the psch 1, the transmit power of the channel psch 1 may be determined according to existing protocols and will not be described in detail here. The UE may then allocate transmit power for the PSFCH 2. Transmitted work P of PSFCH2PSFCH2Can be min { PCMAX-PPSFCH1,Ptypical}. Wherein, min { P }CMAX-PPSFCH1，PtypicalMeans to select PCMAX-PPSFCH1、PtypicalMinimum value of (1), PCMAXRepresenting the maximum transmit power of the user equipment, in particular, PCMAXMay represent the maximum transmit power of the user equipment on the element carrier.

And PtypicalMay include the number of frequency domain resources (e.g., the number of resource blocks and/or the number of subchannels, etc.) of the PSFCH1, and/or the path loss of the direct link of the UE, etc.
For another example, assume that there are two PSFCHs, where PSFCH1 is associated with PSSCH1, PSFCH2 is associated with PSSCH2, PSSCH1 carries CSI, and PSSCH2 carries HARQ feedback information with a lower priority than CSI, when the transmit power of PSFCH1 can be allocated preferentially. Suppose PPSFCH1Indicating the transmit power of the psch 1, the transmit power of the channel psch 1 may be determined according to existing protocols and will not be described in detail here. The UE may then allocate transmit power for the PSFCH 2. Transmitted work P of PSFCH2PSFCH2Can be min { PCMAX-PPSFCH1,Ptypical}. Wherein, min { P }CMAX-PPSFCH1，PtypicalMeans to select PCMAX-PPSFCH1、PtypicalMinimum value of (1), PCMAXRepresenting the maximum transmit power of the user equipment, in particular, PCMAXCan represent the maximum transmitting power, P, of the user equipment on the unit carriertypicalRepresenting at least the transmit power associated with the number of frequency domain resources of the PSFCH 1.
For another example, the control information is different control information, and includes SR information, HARQ feedback information, and CSI, and the priorities of the SR information, the HARQ feedback information, and the CSI are sequentially reduced. Assume that there are 3 PSFCHs, PSFCH1, PSFCH2, and PSFCH 3. The PSFCH1 carries the SR information, the PSFCH2 carries CSI, and the PSFCH3 carries HARQ feedback information. At this time, the UE may first determine the permutation order of the PSFCHs according to the SR information, the HARQ feedback information, and the priority of the CSI, so as to implement allocating the transmit power of the PSFCH1 preferentially, then allocating the transmit power of the PSFCH2, and finally allocating the transmit power of the PSFCH 3.
In a specific implementation, for the PSFCH2 transmitting the HARQ feedback information, its transmit power is min { P }CMAX-PPSFCH1，PtypicalFor the PSFCH3 transmitting the CSI, its transmission power is min { P }CMAX-PPSFCH1-PPSFCH2，Ptypical}.

In a specific implementation, there may be multiple channels for transmitting the same kind of control information, for example, there are M1 PSFCHs for transmitting HARQ feedback information, M2 PSFCHs for transmitting SR information, M3 PSFCHs for transmitting CSI information, and M1, M2, and M3 are positive integers greater than 2, where if priorities of SR, HARQ feedback information, and CSI information are sequentially reduced, then an order of transmission power allocation of each PSFCH is: the transmission power of the M2 PSFCHs transmitting the SR is allocated first, then the transmission power of the M1 PSFCHs transmitting the HARQ feedback information is allocated, and finally the transmission power of the M3 PSFCHs transmitting the CSI information is allocated. For each PSFCH in which the same kind of control information is transmitted, power allocation may still be performed according to the embodiments of the present invention provided herein, and details are not described here.
