In order to better understand the technical solutions of the embodiments of the present application, the following describes technical contents related to the embodiments of the present application.

(1) Augmented reality (eXtended Reality, XR) service

XR refers to all real and virtual combined environments and human-machine interactions produced by computer technology and wearable devices. It includes representative forms of augmented Reality (Augmented Reality, AR), mixed Reality (MR), virtual Reality (VR), and the like, as well as the cross-domain between them. The level of the virtual world is from a partially sensory input to a fully immersive virtual reality. One key aspect of XR is the expansion of human experience, especially experience related to sense of presence (represented by VR) and cognition learning (represented by AR).

For VR service, uplink (UL) is mainly transmitted by denser small data packets, and the small data packets can bear information such as gestures, control, touch and the like and serve as input and reference of downlink presentation data; the downlink mainly transmits multimedia data such as video and audio, and provides immersive feeling for users through timely receiving and presenting the multimedia data. Taking downstream video data as an example, the data packet arrives periodically or quasi-periodically, the data rate can reach several tens or even hundreds of Mbps, the typical value of FPS (frame rate) is 60 or 120, the interval between adjacent data packets is approximately 1/FPS seconds, these data generally need to be successfully transmitted within 10ms on the air interface, and the transmission success rate is required to be not lower than 99% or even 99.9%.

For AR service, uplink may transmit multimedia data such as video and audio in addition to the above dense small data packet transmission, and its service characteristics are similar to those of downlink, and the data rate is usually relatively low, for example, at most several tens Mbps, and the time limit of air interface transmission may be widened, for example, power transmission is generally required in 60ms, and in addition, for XR UL video service, the packet size may be changed for different frames; the downlink data transmission characteristics are substantially consistent with VR traffic.

(2)CG PUSCH

The uplink CG PUSCH transmission, which is a low latency, low overhead uplink transmission scheme, mainly includes type1 (type 1) and type 2 (type 2) CG PUSCHs. Wherein the type 1CG PUSCH is directly validated after radio resource control (Radio Resource Control, RRC) configuration (including periodicity, slot offset within periodicity, time-frequency domain resources, etc.), without requiring additional activation signaling. the type 2CG PUSCH requires not only RRC configuration but also L1 signaling (DCI) activation before it takes effect. CG PUSCH is used in typical traffic scenarios such as high reliability and low latency communications (Ultra-reliable and Low Latency Communications, URLLC), and NR Rel-16 has further been enhanced for CG PUSCH in order to further meet the requirements of URLLC traffic for lower latency and higher reliability. Rel-16 supports the network side to simultaneously configure and activate multiple sets of type1 and/or type 2CG PUSCHs for the UE.

Fig. 2 is a schematic diagram of type 1 and type 2CG PUSCHs provided by an embodiment of the present application, where resources are semi-statically preconfigured through a network, and when a data packet arrives, the data packet may be directly transmitted on the configured or activated CG resources.

To further improve the reliability of the transmission, a configuration grant (configured grant) supports the repeated transmission (Repetition) of one Transport Block (TB). The number of retransmissions and the redundancy version (Redundancy version, RV) sequence corresponding to the retransmissions are configured by RRC.

The uplink power allocation method provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

Fig. 3 is a flow chart of an uplink power allocation method according to an embodiment of the present application, as shown in fig. 3, where the method includes the following steps:

Step 300, the terminal determines a power allocation priority of uplink transmission carrying first uplink control information UCI, where the first UCI is used to indicate a transmission opportunity of a configured grant physical uplink shared channel CG PUSCH that is not used by the terminal, and/or is used to indicate the end of a data burst of the terminal.

Step 301, the terminal performs power allocation on uplink transmission carrying the first UCI according to the power allocation priority of uplink transmission carrying the first UCI.

Optionally, the first UCI may include UCI for indicating a CG PUSCH transmission occasion that the terminal does not use, and/or UCI for indicating the end of a data burst (end of data burst) of the terminal. The CG PUSCH transmission occasion for indicating that the terminal is not used may also be interpreted as CG PUSCH resources/transmission occasions for indicating that the terminal is not used/releasable/redundant. For example, on a certain or certain configured or activated CG PUSCH transmission occasions, the terminal does not have corresponding traffic to be transmitted, and then the terminal may instruct, through the first UCI, the base station that these CG PUSCH transmission occasions will not have data to be transmitted, and the base station may perform other scheduling or transmission on these resources.

Optionally, the first UCI may be part of an existing UCI type (e.g., CG-UCI) and/or an extended part (e.g., adding new bit information to indicate an unused CG PUSCH transmission occasion based on existing CG-UCI bit information) (e.g., using existing CG-UCI bit information to indicate an unused CG PUSCH transmission occasion), or may be a new UCI. The first UCI may be transmitted on PUCCH and/or PUSCH.

Optionally, the uplink transmission carrying the first UCI may include PUCCH transmission carrying the first UCI or PUSCH transmission carrying the first UCI.

Before the terminal performs uplink transmission, the transmission power of different uplink transmissions needs to be determined, and is limited by the transmission power of the terminal, when the terminal is to perform multiple uplink transmissions simultaneously, the total power of the multiple uplink transmissions may exceed the maximum transmission power of the terminal. It may be understood that in this case, the terminal may determine, for the plurality of uplink transmissions, the power allocation priorities of the different uplink transmissions, and reduce, according to the priority order, the transmission power allocated for the uplink transmission with a low partial priority so as to ensure that the total transmission power of the plurality of uplink transmissions does not exceed the maximum transmission power, while ensuring the transmission power of the uplink transmission with a high priority.

For UCI indicating the transmission opportunity of the CG PUSCH that is not used by the terminal, timely and correct reception of the information is helpful for the base station to recycle the unused resource, and is beneficial to improving the utilization rate and throughput of the system resource. Or for UCI indicating the end of the data burst of the terminal (end of data burst), timely and correctly receiving the information helps the base station to reasonably allocate transmission resources for the terminal. Therefore, consideration needs to be given to guaranteeing power allocation of channels transmitting these UCI indications.

Optionally, the determining, by the terminal, a power allocation priority of uplink transmission carrying the first UCI includes:

The terminal determines the power allocation priority of uplink transmission carrying a first UCI according to the first priority order;

In the first priority order, for uplink transmissions having the same priority index, the power allocation priority of the first uplink transmission is the same as the power allocation priority of the second uplink transmission;

The first uplink transmission includes PUCCH transmission carrying the first UCI or PUSCH transmission carrying the first UCI; the second uplink transmission includes a PUCCH transmission carrying at least one of a hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat request-ACKnowledgment, HARQ-ACK), a scheduling request (Scheduling Request, SR), a link recovery request (Link Recovery Request, LRR), or a PUSCH transmission carrying a HARQ-ACK.

For example, when determining the power allocation priority, the terminal may determine the power allocation priority of the PUCCH transmission or the PUSCH transmission according to the priority index (priority index) of the PUCCH transmission or the PUSCH transmission, where the PUCCH transmission or the PUSCH transmission with a higher priority index has a higher power allocation priority.

For uplink transmissions with the same priority index, the terminal may determine, according to the first priority order, that the power allocation priority of the first uplink transmission (i.e. the PUCCH transmission carrying the first UCI or the PUSCH transmission carrying the first UCI) is the same as the power allocation priority of the second uplink transmission, and then the terminal may perform power allocation on the first uplink transmission according to the power allocation priority of the second uplink transmission. The power allocation priority of the second uplink transmission may be determined according to an existing power allocation priority ordering scheme or any other scheme, which is not limited herein.

Note that, in the present application, the priority index is a priority used to represent uplink transmission in the NR protocol (note that, here, the priority is a physical layer priority, and not a power allocation priority), the priority index is 1 for a high priority, and the priority index is 0 for a low priority.

Alternatively, the priority index of the first uplink transmission may be 1 (the corresponding physical layer priority is high priority) or 0 (the corresponding physical layer priority is low priority). The priority or priority index of the first uplink transmission may be predefined by the protocol, for example, the protocol predefines the priority of the first uplink transmission as a low priority (or the priority index is 0), or predefines the priority of the first uplink transmission as a high priority (or the priority index is 1); or the priority or priority index of the first uplink transmission may be configured or indicated by the base station; or the priority or priority index of the first uplink transmission is determined according to the priority or priority index of the UCI carried by the first uplink transmission.

Alternatively, the priority index of the first UCI may be 1 (corresponding physical layer priority is high priority) or 0 (corresponding physical layer priority is low priority). The priority or priority index of the first UCI may be protocol predefined, e.g., the protocol predefines the priority of the first UCI as low priority (or priority index of 0), or predefines the priority of the first UCI as high priority (or priority index of 1); or the priority or priority index of the first UCI may be base station configured or indicated; or the priority or priority index of the first UCI is the same as the priority or priority index of the uplink transmission (e.g., PUCCH or PUSCH) in which it is located.

Optionally, in the first priority order, the order of the power allocation priorities from high to low is: PRACH transmission on the primary cell (PRIMARY CELL, PCELL), PUCCH transmission or PUSCH transmission, SRS transmission or PRACH transmission on other serving cells than PCell;

Wherein, for PUCCH transmission or PUSCH transmission, PUCCH transmission or PUSCH transmission with higher priority index has higher power allocation priority;

(4) SRS transmission, or PRACH transmission on other serving cells than PCell; wherein the aperiodic SRS transmission has a higher priority than the semi-persistent and/or periodic SRS transmission.

The power threshold may be specificallyAbove-mentionedA linear value of P _CMAX (i) of transmission occasion i. Wherein P _CMAX (i) may be a value of a higher layer configuration.

the terminal determines the power allocation priority of the uplink transmission carrying the first UCI according to the second priority order;

The power allocation priority of the third uplink transmission may be determined according to an existing power allocation priority ordering scheme or any other scheme, which is not limited herein.

Optionally, in the second priority order, the order of the power allocation priorities from high to low is: PRACH transmission on PCell, PUCCH transmission or PUSCH transmission, SRS transmission or PRACH transmission on other serving cells than PCell;
