Description
Technical Field
The present disclosure relates to the field of communications, and in particular, to a communication method and a communication device.
Background
As one of key technologies of the new generation radio access technology (new radio access technology, NR), high Frequency (HF) can provide more spectrum resources, support more antenna numbers, and improve system capacity, has been widely studied. With the increase of frequency, the wavelength of the wireless signal is correspondingly shortened, and the size of the antenna at the two ends of the transceiver can be greatly reduced due to the short wavelength, so that a plurality of antennas can be easily integrated into a panel with limited space. Through the beam shaping technology of multiple antennas, the energy of the transmitted signals is collected in a certain direction for transmission, so that the coverage can be effectively improved, and the communication performance is further improved. Accordingly, the receiver can form a reception beam having directivity, and receive a wireless signal arriving in a certain spatial direction with high gain. With the continued evolution of antenna packaging technology, multiple antenna elements can be more easily nested with a chip to form an antenna panel or antenna array, which makes it possible to configure multiple low-correlation antenna panels (or antenna arrays) at the transmitter. Multiple antenna panels may independently form transmit beams so that one transmitter may transmit data streams over different beams to improve transmission capacity or reliability.
Uplink power control is critical to the overall wireless communication transmission system, on the one hand to meet enough transmit energy per bit to achieve quality of service (quality of service, qoS) and on the other hand to minimize interference to other users of the system. To achieve these objectives, the uplink power control must adapt to the radio propagation channel characteristics. There is a need to study uplink power control schemes that can better accommodate the characteristics of the wireless propagation channel.

In the communication system shown in fig. 1, a network device and a user equipment may be used to perform the method provided in the embodiments of the present application.
The present application will mainly discuss power control of uplink signal transmission in the wireless communication system 100. Power control of uplink signaling is critical to the overall wireless communication system, requiring on the one hand sufficient transmit energy per bit to meet quality of service (QoS) requirements, and on the other hand minimizing interference to other users of the system. To achieve these objectives, the uplink power control must adapt to the radio propagation channel characteristics.
The following will briefly describe the power control specified in the prior protocol 3gpp38.213r15 version for uplink signals, such as Sounding Reference Signals (SRS), physical Uplink Shared Channels (PUSCH), physical Uplink Control Channels (PUCCH), and the like.
Power control of PUSCH
The power allocation of PUSCH is determined by higher layer signaling, or both higher layer signaling and physical layer signaling (DCI), or in a protocol predefined manner. Higher layer signaling refers to radio resource control (radio resource control, RRC) signaling, and/or MAC signaling. Physical layer signaling refers to downlink control information (downlink controlinformation, DCI). The RRC signaling configuration may be open loop power control parameters and the DCI may indicate closed loop power control parameters. However, in a specific scenario, the user equipment uses the same power control parameter to determine the transmission power of different PUSCHs.
Based on the power control parameters defined in PUSCH configies, PUSCH transmission power is specified in the existing protocol 3gpp38.213r15 release, specifically as follows:
if the UE uses the set configuration with index value j and the PUSCH power control adjustment status value with index value l in the partial bandwidth b of the carrier f of the serving cell c, the UE determines that the transmission power of the PUSCH at the transmission occasion i is
P CMAX,f,c (i) Is the UE maximum transmission power configured at PUSCH transmission occasion i for carrier f of serving cell c.
Is composed of member P O_NOMINAL_PUSCH,f,c (j) And member P O_UE_PUSCH,b,f,c (j) And one parameter of the composition, where j e {0,1,..j-1 }. />The target power is a target power that includes a cell specific component (cell specific component) and a UE specific component (specific component).
Representing the number of physical resource blocks (physical resource block, PRBs) occupied by the UE transmitting PUSCH at the ith PUSCH transmission opportunity;
PL b,f,c (q d ) Is the reference signal index q of the UE through the downlink BWP d The path loss calculated for the corresponding reference signal paired with the carrier f uplink BWPb of serving cell c.
f b,f,c (i, l) power control adjustment for closed loop power control (TPC).
α b,f,c (j) Is the scaling factor of the path loss (path loss).
α b,f,c (j) Can be taken as [0,0.4,0.5,0.6,0.7,0.8,0.9,1 ]]。
Δ TF,b,f,c (i) Transmission related, such as modulation, target coding rate, code Block (CB) size, PUSCH content, is applicable only for single layer transmission.
i is defined by the slot index, the first symbol S within the slot, and a plurality of consecutive symbols L.
j is an index of the open loop parameter.
l is an index of the closed loop power control state.
q d Is the RS resource index for path loss measurement.
The other parameters and the calculation method of the values thereof in the above formula (1) can refer to the protocol 3gpp38.213r15, and are not described herein.
It can be seen that the power control parameters of PUSCH are configured by higher layer signaling, or by a combination of higher layer signaling and physical layer signaling, but each PUSCH resource corresponds to only one set of power control parameters. When the UE transmits PUSCH to a plurality of panels or a plurality of TRPs of one TRP using one or a plurality of panels, the transmission paths of the UE and the different panels or TRPs are different, and the channel conditions are also different. If the same power control parameters are still used, then the power utilization efficiency is low.
Power control of PUCCH
The manner of determining PUCCH transmit power based on PUCCH power control parameters is similar to the power control mechanism of PUSCH, and reference may be made specifically to 3gpp38.331r15 version, 3gpp38.213r15 version. PUCCH transmission power is specified in the existing protocol 3gpp38.213r15 release, as follows:
if the UE uses the PUCCH power control adjustment state value with index value of l at partial bandwidth b of carrier f of primary cell c, the UE determines that the transmission power of PUCCH at transmission occasion i is P PUCCH,b,f,c (i,q u ,q d ,l):
P CMAX,f,c (i) Is the UE maximum transmit power configured at PUSCH transmission occasion i for carrier f of serving cell c.
By member P O_NOMINAL_PUCCH And member P O_UE_PUCCH (q u ) And one parameter of the composition.The target power is a target power that includes a cell specific component (cell specific component) and a UE specific component (specific component).
Indicating the number of Physical Resource Blocks (PRBs) occupied by the UE transmitting PUCCH at the i-th PUCCH transmission opportunity.
Δ TF,b,f,c (i) In connection with transmission. For example, delta TF,b,f,c (i) Related to the following: PUCCH format, # symbols, uplink control information (uplink control information, UCI) type, UCI payload size, coding scheme, and different effective coding rates.
g b,f,c (i, l) power control adjustment for closed loop power control (TPC).
Δ F_PUCCH (F) With respect to PUCCH formats, RRC has only one value per PUCCH format.
i is defined by the slot index, the first symbol S within the slot, and a plurality of consecutive symbols L.
q u Is an index of the open loop parameters.
l is an index of the closed loop power control state.
q d Is used forRS resource index for path loss measurement.
PUCCH has the same problem as PUSCH and will not be described here.
Power control for srs
Based on the power control parameters defined in the SRS-resource set domain, the SRS transmission power is specified in the existing protocol 3gpp38.213r15 version, specifically as follows:
If the UE uses the SRS power control adjustment state value with the index value of l in the partial bandwidth b of the carrier f of the serving cell c, the SRS transmission power sent by the UE at the SRS transmission time i is P SRS,b,f,c (i,q s ,l):
P CMAX,f,c (i) The maximum UE transmit power configured at SRS transmission timing i for carrier f in serving cell c.
Is configured for carrier f uplink BWPb of serving cell c by higher layer parameter p 0. SRS resource set q s Is configured by the higher layer parameters SRS-ResourceSet and SRS-ResourceSetId. />To characterize the target received power.
M SRs,b,f,c (i) Representing the number of physical resource blocks occupied by the UE to transmit SRS at the ith SRS transmission opportunity.

h b,f,c (i, l) is the reference signal index q of the UE over downlink BWP d Calculated path loss of the reference signalSRS resource set q of carrier f uplink BWPB with serving cell c s Pairing. Wherein, with SRS resource set q s Associated reference signal index q d Is defined by ssb Index (for indicating the resource Index of SS/PBCH) in the higher-layer parameter pathassreference RS or CSI RS Index (for indicating the resource Index of CSI RS) in the higher-layer parameter pathassreference RS. Is a path loss measurement based on RSRP by the terminal. h is a b,f,c (i, l) power control adjustment for closed loop power control (TPC).
i is defined by the slot index, the first symbol S within the slot, and a plurality of consecutive symbols L.
l is an index of the closed loop power control state.
q d Is the RS resource index for path loss measurement.
q s Is the SRS resource set ID.
The other parameters and the calculation method of the values thereof involved in the algorithm can refer to the protocol 3gpp38.213r15, and are not described herein.
The SRS has the same problems as PUSCH and PUCCH, and will not be described in detail here.
In order to better adapt to the characteristics of the wireless propagation channel and achieve the improvement of the power efficiency and the uplink transmission performance of uplink transmission, the application provides some possible communication methods. As will be described in detail below.
Examples of several scenarios that may be used for the communication method provided in the present application are described below. In this embodiment of the present application, associating the ue with 1 panel means that the ue configures the panel with the maximum transmission power. The user equipment being associated with a plurality of panels means that the user equipment is configured with maximum transmission power for each of the plurality of panels. In this embodiment of the present application, the maximum transmission power or transmission power of the ue associated with 1 panel refers to the maximum transmission power or transmission power configured by the panel. The maximum transmission power or transmission power of the user equipment associated with the plurality of panels refers to the maximum transmission power or transmission power at which the plurality of panels are each configured. For example, the maximum transmission power of panel 1 is configured as maximum transmission power 1, the maximum transmission power of panel2 is configured as maximum transmission power 2, and the maximum transmission power 1 and the maximum transmission power 2 are the same or different. Associating a user equipment with one or more TRPs means that the user equipment has a communication link or connection with the one or more TRPs. In the embodiment of the present application, the maximum transmission power or transmission power of the ue associated with 1 TRP refers to the configured maximum transmission power or transmission power for the TRP. The maximum transmission power or transmission power of the user equipment associated with the plurality of TRPs refers to the maximum transmission power or transmission power configured for each of the plurality of TRPs. Taking the example that the user equipment is associated with the panel 1 and the panel2, the uplink channel or signal associated with the panel 1 refers to the uplink channel or signal being sent by the panel 1, and the uplink channel or signal associated with the panel2 refers to the uplink channel or signal being sent by the panel 2. Taking the example that the user equipment is associated with TRP1 and TRP2, the uplink channel or signal associated with TRP1 refers to that the uplink channel or signal is towards TRP1, or the uplink channel or signal associated with TRP1 refers to that the target transmission receiving point of the uplink channel or signal is TRP1; an uplink channel or signal associated with TRP2 means that the uplink channel or signal is TRP 2-oriented or an uplink channel or signal associated with TRP2 means that the target transmission reception point of the uplink channel or signal is TRP2.

Taking the example that the user equipment is associated with the panel 1 and the panel 2, it may be assumed that the maximum transmission power associated with the panel 1 is the first maximum transmission power and the maximum transmission power associated with the panel 2 is the second maximum transmission power. Taking the example that the user equipment is associated with TRP1 and TRP2, it may be assumed that the maximum transmission power associated with TRP1 is the first maximum transmission power and the maximum transmission power associated with TRP2 is the second maximum transmission power.
Optionally, the uplink channel or signal associated with panel 1 and the uplink channel or signal associated with panel 2 overlap or partially overlap in the time domain. Optionally, the maximum transmission power is for a certain transmission opportunity of a certain BWP of a certain carrier of a certain cell for the user equipment; here, a plurality of TRPs belong to the same cell.
Scene 2: the user equipment is configured with a maximum transmit power associated with one or more of the panels or with one or more of the TRPs, and a sum of the maximum transmit powers associated with all of the panels or with all of the TRPs is greater than a maximum transmit power at a cell level of the user equipment. Taking the example that the user equipment is associated with the panel 1 and the panel 2, it may be assumed that the maximum transmission power associated with the panel 1 is the first maximum transmission power and the maximum transmission power associated with the panel 2 is the second maximum transmission power.
The upstream channel or signal associated with Panel 1 and the upstream channel or signal associated with Panel 2 overlap or partially overlap in the time domain.

Scene 3: the user equipment is configured with a maximum transmit power associated with one or more of the panels or with one or more of the TRPs, and a sum of the maximum transmit powers associated with all of the panels or with all of the TRPs is greater than a maximum transmit power at a cell level of the user equipment. Taking the example that the user equipment is associated with the panel 1 and the panel 2, it may be assumed that the maximum transmission power associated with the panel 1 is the first maximum transmission power and the maximum transmission power associated with the panel 2 is the second maximum transmission power. The upstream channel or signal associated with Panel 1 and the upstream channel or signal associated with Panel 2 do not overlap in the time domain. In scenario 3, the user equipment may perform the method flow in fig. 2 to determine the transmit power of the first uplink channel or signal associated with panel 1 and to determine the transmit power of the second uplink channel or signal associated with panel 2. Optionally, the maximum transmission power is for a certain transmission opportunity of a certain BWP of a certain carrier of a certain cell for the user equipment; here, a plurality of TRPs belong to the same cell.

Taking the example that the user equipment is associated with the panel 1 and the panel 2, optionally, the uplink channel or signal associated with the panel 1 and the uplink channel or signal associated with the panel 2 overlap or partially overlap in the time domain. Optionally, the maximum transmission power is for a certain transmission opportunity of a certain BWP of a certain carrier of a certain cell for the user equipment; here, a plurality of TRPs belong to the same cell.
It may be understood that, in this embodiment of the present application, the maximum transmission power is not limited for a certain transmission opportunity of a certain BWP of a certain carrier of a certain cell, and is not described herein.

It should be understood that the communication scheme provided in the present application may also be employed when the ue determines the transmission power of three or more uplink channels or signals that overlap in the time domain. For example, uplink channel 1, uplink channel 2, and uplink channel 3 of the ue overlap or partially overlap in the time domain; the user equipment determines the transmission power of an uplink channel 1 as transmission power 1, determines the transmission power of an uplink channel 2 as transmission power 2, and determines the transmission power of an uplink channel 3 as transmission power 3; if the sum of the transmission power 1, the transmission power 2 and the transmission power 3 is larger than the maximum transmission power of the cell level of the user equipment, the user equipment determines the transmission power of a third uplink channel or signal according to the path loss and the fourth maximum transmission power; the fourth maximum transmission power is the maximum transmission power of the cell level of the user equipment minus the transmission power 1 and the transmission power 2.

F is a real number greater than 0. In one possible implementation, the ue may gradually decrease the second transmission power until the sum of the fourth transmission power and the first transmission power is less than or equal to the maximum transmission power of the cell level of the ue. For example, the user equipment first reduces the second transmit power by ten percent; if the sum of the second transmission power and the first transmission power is larger than the maximum transmission power of the cell level of the terminal equipment after the second transmission power is reduced, the user equipment reduces the second transmission power by twenty percent; and so on until the sum of the second transmission power and the first transmission power after the second transmission power is reduced is less than or equal to the maximum transmission power of the cell level of the terminal equipment.
604. And under the condition that the fourth transmission power is lower than the first threshold, the user equipment discards the transmission of the second uplink channel or signal.
