The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
An embodiment of the present invention provides an uplink multi-beam power control method, which is applied to a terminal, and as shown in fig. 2, the method specifically includes the following steps:
step 21: and acquiring resource identification information of at least two sending beams corresponding to the target channel or the target signal.
The terminal receives resource identification information sent by the network equipment, wherein the resource identification information is used for indicating: the target channel or target signal corresponds to at least two (multiple) transmit beams. Specifically, the target channel includes: at least one channel of a physical uplink shared channel NR-PUSCH, a physical uplink control channel NR-PUCCH and a physical random access channel NR-PRACH, wherein the target signal comprises: a channel sounding reference signal.
Specifically, since the terminal supports multi-beam transmission, the network device may configure multiple different transmit beams (uplink beams) for the same target channel or target signal, e.g., beams 0 to 3 for NR-PUCCH, beams 4 to 7 for NR-PUSCH, and beams 8 to 9 for NR-PRACH.
In order to avoid the problem that the total transmission power of a plurality of beams when the plurality of beams are simultaneously transmitted may exceed the maximum transmission power of the terminal due to the fact that the terminal supports multi-beam transmission, thereby causing transmission failure, the embodiment of the present invention may limit the total transmission power of the plurality of beams within the maximum transmission power range of the terminal through the following steps.
Step 22: and if the total transmitting power of at least two transmitting beams corresponding to the resource identification information exceeds the maximum transmitting power of the terminal, transmitting an uplink signal to the base station through part of the transmitting beams.
Step 22 means that the terminal actively selects a part of beams in a plurality of sending beams corresponding to the NR-PUSCH, NR-PUCCH, NR-PRACH, or NR-SRS Multi-beam to send uplink signals, so as to ensure that the total sending power of the sending beams is limited within the maximum sending power range of the terminal, ensure normal transmission of each sending beam, and further ensure the reliability of beam transmission of a target channel or a target signal.
Step 23: and if the total transmitting power of at least two transmitting beams corresponding to the resource identification information exceeds the maximum transmitting power of the terminal, adjusting the total transmitting power of the transmitting beams to be below the maximum transmitting power and then transmitting the uplink signal to the base station.
Step 23 refers to the terminal actively adjusting the transmission power of some or all of the plurality of transmission beams corresponding to the NR-PUSCH, NR-PUCCH, NR-PRACH, or NR-SRS Multi-beam to ensure that the total transmission power of the transmission beams is limited within the maximum transmission power range of the terminal, ensure the normal transmission of each transmission beam, and further ensure the reliability of the beam transmission of the target channel or the target signal.
Step 24: and if the total transmitting power of at least two transmitting beams corresponding to the resource identification information exceeds the maximum transmitting power of the terminal, grouping the transmitting beams and respectively transmitting uplink signals to the base station through the grouped transmitting beams.
Step 24 means that the terminal groups a plurality of transmission beams corresponding to NR-PUSCH, NR-PUCCH, NR-PRACH, or NR-SRS Multi-beam, and transmits uplink signals to the network device by each group, so as to ensure that the total transmission power of each group of transmission beams is limited within the maximum transmission power range of the terminal, ensure normal transmission of each transmission beam, and further ensure the reliability of beam transmission of the target channel or the target signal.
The uplink multi-beam power control method according to the embodiment of the present invention is briefly introduced above, and is further described with reference to specific application scenarios. The same or different target signals may correspond to different transmission beams, different beams correspond to scenes, and different power control modes. Wherein,
in the first method, a single target channel or target signal may correspond to at least two transmission beams, that is, the same target channel or target signal corresponds to multiple different transmission beams, if at least two transmission beams correspond to the same target channel or target signal, step 22 specifically includes: determining the rest beams except the last M beams in the arrangement sequence as first target transmission beams according to the arrangement sequence from excellent transmission quality to poor transmission quality of the transmission beams; and transmitting an uplink signal to the base station through the first target transmission beam. Wherein M is a positive integer, and the total transmit power of the first target transmit beam is lower than or equal to the maximum transmit power. Wherein the value of M is less than the maximum number of beams of the transmission beam corresponding to the target channel or the target signal. Specifically, when it is detected that the total transmission power of the plurality of transmission beams corresponding to the target channel or the target signal exceeds the maximum transmission power, one beam with the worst beam transmission quality is discarded first, and whether the total transmission power of the remaining beams is lower than the maximum transmission power is detected, if so, the discarding of other transmission beams is stopped, and if still higher than the total transmission power, the beam with the worst beam transmission quality in the remaining beams is discarded continuously until the total transmission power of the remaining beams is lower than the maximum transmission power.
Specifically, determining remaining beams other than the last M beams in the ranking order as the first target transmission beam according to the ranking order in which the transmission quality of the transmission beams is from good to bad includes: acquiring the transmission quality of each transmitting beam, and sequencing the transmitting beams from excellent to poor according to the transmission quality to obtain a sequencing order; discarding the last M beams in the ranking order and detecting whether the total transmit power of the remaining beams is lower than or equal to the maximum transmit power; if the first target transmission beam is lower than or equal to the second target transmission beam, determining the remaining beam as the first target transmission beam.
Further, the transmission quality of the transmission beam may be determined by detecting the beam path loss or the beam reception power. Specifically, the step of determining the first target transmission beam specifically includes: the method comprises the steps of obtaining the beam path loss of each transmitting beam, sequencing each transmitting beam according to the beam path loss from low to high to obtain a sequencing order, discarding the last M beams in the sequencing order, detecting whether the total transmitting power of the rest beams is lower than or equal to the maximum transmitting power, and determining the rest beams as first target transmitting beams if the total transmitting power of the rest beams is lower than or equal to the maximum transmitting power.
Alternatively, the transmission quality may also be determined by detecting the beam received power, specifically, the step of determining the first target transmission beam specifically includes: the method comprises the steps of obtaining the beam receiving power of receiving beams corresponding to all the sending beams, sequencing the corresponding sending beams according to the beam receiving power from high to low to obtain a sequencing order, discarding the last M beams in the sequencing order, detecting whether the total transmitting power of the rest beams is lower than or equal to the maximum transmitting power, and determining the rest beams as first target sending beams if the total transmitting power of the rest beams is lower than or equal to the maximum transmitting power.
The network side is assumed to configure the terminal to transmit the NR-PRACH in a multi-beam transmission mode, and the terminal supports 2-beam transmission of the NR-PRACH to the maximum extent. Wherein, the 1 st wave beam reference signal receiving power is larger than the 2 nd wave beam reference signal receiving power, the total transmitting power of the 2 transmitting wave beams exceeds the maximum transmitting power of the terminal and the transmitting power of each transmitting wave beam is lower than the maximum transmitting power of the terminal, and the terminal abandons the 2 nd wave beam of the NR-PRACH to transmit. Therefore, the sending beams with poor transmission quality are discarded to ensure that the total transmitting power is limited within the maximum transmitting power range of the terminal, the normal transmission of each sending beam is ensured, and the beam transmission reliability of the target channel or the target signal is further ensured.
In a second mode, a single target channel or target signal may correspond to at least two transmission beams, that is, the same target channel or target signal corresponds to a plurality of different transmission beams, and if at least two transmission beams correspond to the same target channel or target signal, step 22 may also be implemented by: determining randomly selected N of the transmission beams as second target transmission beams; and transmitting the uplink signal to the base station through the second target transmission beam. Wherein N is a positive integer, and the total transmit power of the second target transmit beam is lower than or equal to the maximum transmit power.
The method randomly selects the transmitting beams of the NR-PUSCH or the NR-PUCCH or the NR-PRACH or the NR-SRS for the terminal so as to ensure that the total transmitting power of the transmitting beams is limited within the maximum transmitting power range of the terminal, ensure the normal transmission of each transmitting beam and further ensure the beam transmission reliability of a target channel or a target signal.
In a third mode, a single target channel or target signal may correspond to at least two transmission beams, that is, the same target channel or target signal corresponds to multiple different transmission beams, and if at least two transmission beams correspond to the same target channel or target signal, step 23 specifically includes: adjusting the transmit power of each transmit beam until the total transmit power of the transmit beams is less than or equal to the maximum transmit power; and transmitting the uplink signal to the base station by the transmitting beam after the transmitting power is adjusted.
The method actively adjusts the transmitting power of part or all of the multiple transmitting beams corresponding to the NR-PUSCH or NR-PUCCH or NR-PRACH or NR-SRS for the terminal, so as to ensure that the total transmitting power of the transmitting beams is limited within the maximum transmitting power range of the terminal, ensure the normal transmission of each transmitting beam, and further ensure the beam transmission reliability of the target channel or the target signal.
In a fourth mode, a single target channel or target signal may correspond to at least two transmission beams, that is, the same target channel or target signal corresponds to multiple different transmission beams, and if at least two transmission beams correspond to the same target channel or target signal, step 24 specifically includes: at least two transmitting wave beams are divided into a plurality of groups, and uplink signals are respectively transmitted to the base station through the plurality of groups of transmitting wave beams of time division multiplexing. Wherein the total transmit power of each group of transmit beams is less than or equal to the maximum transmit power.
The method is that the terminal sends a plurality of beams corresponding to NR-PUSCH or NR-PUCCH or NR-PRACH or NR-SRS in turn according to a time division mode, so as to ensure that the total transmitting power of each group of transmitting beams is limited within the maximum transmitting power range of the terminal, ensure the normal transmission of each transmitting beam, and further ensure the beam transmission reliability of a target channel or a target signal.
In a fifth mode, the multiple target channels or target signals may correspond to at least two transmission beams, that is, different target channels or target signals correspond to multiple different transmission beams, and if at least two transmission beams correspond to different target channels or target signals, step 22 specifically includes: according to sequences from high to low of priorities of different target channels or target signals, last P first target channels or first target signals in the sequences are obtained; discarding a part of beams in the first target channel or the first target signal, and determining remaining beams except the discarded beams as third target transmission beams; and transmitting the uplink signal to the base station through the third target transmission beam. Wherein the priority of the target channel or the target signal is preconfigured or configured by the network device and notified to the terminal, P is a positive integer, and the total transmission power of the third target transmission beam is lower than or equal to the maximum transmission power.
The above process of discarding P target channels or partial beams of the target signal may be performed by discarding one target channel or partial beam of the target signal at a time, specifically, when it is detected that the total transmission power of multiple transmission beams corresponding to the target channel or the target signal exceeds the maximum transmission power, first discarding the one target channel or partial beam of the target signal with the lowest priority, and detecting whether the total transmission power of all the target channels and the remaining beams of the target signal is lower than the maximum transmission power, if so, stopping discarding other transmission beams, and if still higher than the total transmission power, continuing to discard the target channel or partial beam of the target signal with the lowest priority in the remaining target channels and the target signal until the total transmission power of all the target channels and the remaining beams of the target signal is lower than the maximum transmission power.
The method comprises the steps that a network side is assumed to configure a terminal to transmit NR-PRACH and NR-PUSCH in a multi-beam transmission mode, the terminal supports 3-beam transmission at most, the 1 st beam is used for NR-PRACH transmission, the 2 nd and 3 rd beams are used for NR-PUSCH transmission, the total power of the 3 beams exceeds the maximum transmission power of UE, and the transmission power of each transmission beam is lower than the maximum transmission power of the terminal. The priority of the NR-PRACH is higher than that of the NR-PUSCH, and then the terminal discards one transmission beam corresponding to the NR-PUSCH and having poor beam quality, so as to ensure that the total transmission power of the transmission beams corresponding to the NR-PRACH and the NR-PUSCH is limited within the maximum transmission power range of the terminal, ensure normal transmission of each transmission beam, and further ensure the reliability of beam transmission of the target channel or the target signal. When each target channel or target signal only corresponds to one transmission beam, the total transmission power of each transmission beam can be guaranteed to be limited within the maximum transmission power range of the terminal by adjusting the transmission power of the transmission beam corresponding to the target channel or target signal with lower priority.
In a sixth mode, the plurality of target channels or target signals may correspond to at least two transmission beams, that is, different target channels or target signals correspond to a plurality of different transmission beams, and if at least two transmission beams correspond to different target channels or target signals, step 22 may be further implemented by: determining Q randomly selected beams in the transmitting beams corresponding to each target channel or target signal as a fourth target transmitting beam; and transmitting the uplink signal to the base station through the fourth target transmission beam. Wherein Q is a positive integer, and the total transmit power of the fourth target transmit beam is lower than or equal to the maximum transmit power.
The method randomly selects the transmitting beams of NR-PUSCH, NR-PUCCH, NR-PRACH and NR-SRS for the terminal to ensure that the total transmitting power of the transmitting beams is limited in the maximum transmitting power range of the terminal, ensure the normal transmission of each transmitting beam and further ensure the reliability of the beam transmission of the target channel or the target signal.
In the seventh mode, the multiple target channels or target signals may correspond to at least two transmission beams, that is, different target channels or target signals correspond to multiple different transmission beams, and if at least two transmission beams correspond to different target channels or target signals, step 23 specifically includes: respectively adjusting the transmitting power of each transmitting beam corresponding to each target channel or target signal until the total transmitting power of the transmitting beams is lower than or equal to the maximum transmitting power; and transmitting the uplink signal to the base station by the transmitting beam after the transmitting power is adjusted.
The method actively adjusts the transmitting power of part or all of the multiple transmitting beams corresponding to the NR-PUSCH, the NR-PUCCH, the NR-PRACH and the NR-SRS for the terminal so as to ensure that the total transmitting power of the transmitting beams is limited within the maximum transmitting power range of the terminal, ensure the normal transmission of each transmitting beam and further ensure the beam transmission reliability of a target channel or a target signal.
In the eighth mode, the multiple target channels or target signals may correspond to at least two transmission beams, that is, different target channels or target signals correspond to multiple different transmission beams, and if at least two transmission beams correspond to different target channels or target signals, step 24 specifically includes: dividing the transmitting wave beams into a plurality of groups according to a target channel or a target signal; and respectively transmitting uplink signals to the base station through multiple groups of time division multiplexing transmission beams. Wherein the total transmit power of each group of transmit beams is less than or equal to the maximum transmit power.
The method is that the terminal sends a plurality of beams corresponding to NR-PUSCH, NR-PUCCH, NR-PRACH and NR-SRS in turn according to a time division mode, so as to ensure that the total transmitting power of each group of transmitting beams is limited within the maximum transmitting power range of the terminal, ensure the normal transmission of each transmitting beam and further ensure the beam transmission reliability of a target channel or a target signal.
If the target channel is a physical random access channel, after step 22, 23 or 24, the terminal further sends indication information for indicating that the beam power climbing is suspended to the base station. Here, when the terminal abandons or adjusts one or more of a plurality of transmission beams corresponding to the NR-PRACH, the terminal will transmit power ramp-up suspension indication information to a higher layer.
If the target channel is a physical uplink shared channel and/or a physical uplink control channel, or the target signal is a channel sounding reference signal, after step 22, 23 or 24, the terminal further sends information carrying the beam power headroom to the base station. Here, when the terminal abandons or adjusts one or more of the plurality of transmission beams corresponding to the NR-PUSCH, NR-PUCCH, and/or NR-SRS, the terminal triggers power headroom reporting and transmits the power headroom to a higher layer.
In the uplink multi-beam power control method of the embodiment of the present invention, when the total transmission power of a plurality of transmission beams corresponding to a target channel or a target signal exceeds the maximum transmission power of a terminal, the total transmission power may be controlled within the maximum transmission power range of the terminal by discarding some of the transmission beams, adjusting the transmission power of each transmission beam, or by multi-beam time division multiplexing, etc., thereby ensuring normal transmission of each transmission beam and further ensuring reliability of beam transmission of the target channel or the target signal.
