Background

Compared with the existing mobile communication system, the future 5G mobile communication system needs to adapt to more diversified scenes and service requirements. The main scenarios of NR (new air interface) include: the method comprises the following steps of mobile broadband enhancement eMBB, large-scale Internet of things mMTC and ultrahigh-reliability ultralow-delay communication URLLC; the scenes put forward the requirements of high reliability, low time delay, large bandwidth, wide coverage and the like for the system.

When the eMBB service and the URLLC service need to be multiplexed, two modes are available: one mode is semi-static resource allocation, transmission of an eMBB service and transmission of a URLLC service are respectively in different resource pools, and under the condition, a part of time-frequency resources are reserved for the URLLC service; due to the dispersion and uncertainty of the URLLC service, the reserved resources can cause the reduction of the resource utilization rate; the other mode is dynamic multiplexing, the transmission of eMBB service and the transmission of URLLC service share the same resource pool, and the base station dynamically schedules eMBB and URLLC transmission for multiplexing; due to the latency requirements of URLLC transmissions, the base station may schedule URLLC transmissions to resources already allocated to eMBB transmissions. For the dynamic multiplexing mode of the eMBB transmission and the URLLC transmission, since reliability of the URLLC transmission is to be ensured, it is necessary to reduce the influence and interference of the eMBB transmission on the URLLC transmission.

In summary, the eMBB terminal and the URLLC terminal perform dynamic multiplexing in the same resource pool, and when transmission of the eMBB service and transmission of the URLLC service overlap in the time domain/frequency domain, the network needs to adjust uplink transmission of the eMBB terminal. In the prior art, a network cannot flexibly process uplink transmission of an eMBB terminal.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

Embodiments of the present invention are described below with reference to the accompanying drawings. The detection method, the transmission method, the terminal and the network side equipment of the advanced indication signal provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, an Evolved Long Term Evolution (lte) system, or a subsequent lte communication system. Referring to fig. 1, an architecture diagram of a wireless communication system according to an embodiment of the present invention is shown. As shown in fig. 1, the wireless communication system may include: the network side device 10 and a terminal (terminal may also be referred to as a user side device), for example, the terminal is denoted as UE11, and the UE11 may be connected to the network side device 10. In practical applications, the connections between the above devices may be wireless connections, and fig. 1 illustrates the connections between the devices by solid lines for convenience and convenience in visual representation.

It should be noted that the communication system may include a plurality of UEs, and the network side device may communicate (transmit signaling or transmit data) with the plurality of UEs.

The network side device 10 provided in the embodiment of the present invention may be a base station, which may be a commonly used base station, an evolved node base station (eNB), or a network side device in a 5G system (for example, a next generation base station (gNB), a Transmission and Reception Point (TRP), or a cell) and other devices.

The terminal provided by the embodiment of the invention can be a Mobile phone, a tablet Computer, a notebook Computer, an Ultra-Mobile Personal Computer (UMPC), a netbook, a Wearable Device, a vehicle-mounted Device or a Personal Digital Assistant (PDA), and the like. It should be noted that the specific type of the terminal is not limited in the embodiment of the present invention.

As shown in fig. 2, an embodiment of the present invention provides an indication method for uplink transmission, which is applied to a terminal, and includes:

step 201, receiving a downlink control signaling, where the downlink control signaling carries a power adjustment instruction for target uplink transmission or a cancellation instruction for instructing a terminal to cancel the target uplink transmission.

In this step, the target uplink transmission is scheduled by the network side device through the uplink grant UL grant. The uplink grant UL grant is transmitted in downlink control information DCI in a physical downlink control channel PDCCH. For example, the network side device sends a PDCCH carrying DCI, where the DCI carries a UL grant for scheduling target uplink transmission. For another example, the target uplink transmission is transmission of a physical uplink shared channel PUSCH.

Preferably, the target uplink transmission may be determined by the terminal according to a latest uplink grant (UL grant) sent by the network side before receiving the downlink control signaling, that is, the target uplink transmission is scheduled in the latest UL grant. Or, the target uplink transmission may also be indicated in the downlink control signaling, such as explicitly indicating a time-frequency resource of the target uplink transmission, or implicitly indicating; for example, the terminal determines the target uplink transmission through the indication of one or more fields in the downlink control signaling.

Step 202, adjusting the transmitting power of the target uplink transmission according to the power adjustment instruction; or canceling the target uplink transmission according to the cancellation indication.

As a preferred embodiment, if the transmit power of the target uplink transmission indicated by the power adjustment is zero, the terminal cancels the target uplink transmission.

It should be noted that, in the above embodiment of the present invention, the power adjustment indication may be specifically indicated by the following two ways:

firstly, directly indicating the transmitting power of target uplink transmission; for example, the transmit power of the target uplink transmission is directly indicated to be x dB.

Secondly, indicating the adjustment range of the transmitting power of the target uplink transmission; for example, if the adjustment amplitude is indicated to be y dB, the transmission power of the target uplink transmission is the current transmission power + y, or the current transmission power-y.

As an embodiment, if the transmit power of the target uplink transmission obtained after the terminal adjusts the transmit power of the target uplink transmission according to the power adjustment indication is zero, the terminal cancels the target uplink transmission.

As another embodiment, if the downlink control signaling received by the terminal directly carries a cancel indication, the terminal directly cancels the target uplink transmission.

Preferably, the UL grant for scheduling target uplink transmission may be sent before the downlink control signaling. For example, after the terminal receives the UL grant for scheduling PUSCH1 transmission, the network side device sends a downlink control signaling to the terminal, and after the terminal receives the downlink control signaling, the terminal adjusts the transmission power of PUSCH1 or cancels the scheduled PUSCH1 transmission according to the downlink control signaling.

As an embodiment, the downlink control signaling includes an indication field;

different indication states of the indication field are used for identifying different power adjustment indications;

and/or the preset indication state of the indication field is used for identifying the cancellation indication.

For example, the indication field contains 4 different indication states, one of which is used to identify the cancellation indication; the remaining three indication states are used to identify different power adjustment indications, respectively. For another example, the indication field contains 2 different indication states, one of which is used to identify the cancellation indication, and the remaining one is not defined; as another example, the indication field contains 4 different indication states, each of which 4 different indication states is used to identify a different power adjustment indication.

For example, a preferred indication of the field is shown in table 1.

TABLE 1

It should be noted that, in the above embodiments of the present invention, the correspondence between the indication state of the indication field and the power adjustment indication and/or the cancellation indication is predefined or configured by the network. The bit number of the indication field can be determined according to the number of indication states of the indication field, for example, if the indication field includes 4 indication states, the indication field can be set to 2 bits; as another example, the indication field contains 8 indication states, and the indication field may be set to 3 bits.

Further, in the foregoing embodiment of the present invention, the downlink control signaling is a dedicated signaling of the terminal, or the downlink control signaling is a group common signaling.

The dedicated signaling of the terminal may be a UL grant scheduling one transport block for initial transmission, or a UL grant scheduling one transport block for retransmission. When the downlink control signaling is a dedicated signaling of the terminal, the indication field in the downlink control signaling may multiplex an existing field in the dedicated signaling of the terminal, or use a newly added field, which is not specifically limited again.

Wherein the group common signaling may be group common power adjustment signaling.

When the downlink control signaling is a group common signaling, the indication field in the downlink control signaling may multiplex an existing DCI format or an existing field in the group common signaling, or use a new DCI format or add a new field in the existing group common signaling, which is not limited specifically herein.

As a preferred embodiment, step 202 includes:

if the time interval between the time when the terminal receives the downlink control signaling and the starting time of the target uplink transmission is greater than or equal to the preset processing time, adjusting the transmitting power of the target uplink transmission according to the power adjustment instruction; or canceling the target uplink transmission according to the cancellation indication.

In short, the downlink control signaling needs to be notified to the terminal before the target uplink transmission of the terminal starts, since the terminal needs time to process the downlink control signaling. If the time interval between the time when the terminal receives the downlink control signaling and the starting time of the target uplink transmission is greater than or equal to the preset processing time, it indicates that the terminal has enough processing time to process the downlink control signaling, and cancel the target uplink transmission or adjust the transmitting power of the target uplink transmission, and the terminal can process the target uplink transmission according to the indication of the downlink control signaling.

Bearing the above example, in the above embodiment of the present invention, the method further includes:

and if the time interval between the time when the terminal receives the downlink control signaling and the starting time of the target uplink transmission is less than the preset processing time, the terminal ignores the downlink control signaling.

If the time interval between the time when the terminal receives the downlink control signaling and the starting time of the target uplink transmission is less than the preset processing time, the terminal is indicated to have insufficient processing time to process the downlink control signaling, and the target uplink transmission is cancelled or the transmitting power of the target uplink transmission is adjusted.

In summary, in the embodiments of the present invention, the network side device sends the downlink control signaling carrying the power adjustment instruction or the cancellation instruction to the terminal, and the terminal adjusts the transmit power of the target uplink transmission according to the power adjustment instruction or cancels the target uplink transmission according to the cancellation instruction, and this indication manner can flexibly indicate the power adjustment or cancellation of the terminal, and implement protection on terminal transmission, thereby improving communication performance.

As shown in fig. 3, an embodiment of the present invention further provides an indication method for uplink transmission, which is applied to a network side device, and includes:

step 301, sending a downlink control signaling to the terminal, where the downlink control signaling carries a power adjustment instruction for target uplink transmission or a cancellation instruction for instructing the terminal to cancel the target uplink transmission.

Preferably, the UL grant for scheduling target uplink transmission may be sent before the downlink control signaling. For example, after sending the UL grant scheduling PUSCH1 transmission to the terminal, the network side device sends a downlink control signaling to the terminal, where the downlink control signaling is used to instruct the terminal to adjust the transmission power of the PUSCH1 or cancel the scheduled PUSCH1 transmission.

As a preferred embodiment, step 301 comprises:

and sending the downlink control signaling to a terminal under the condition that the target uplink transmission scheduled by the network side equipment and other uplink transmissions scheduled by the network side equipment are overlapped on time domain resources and/or frequency domain resources.

For example, when the network side device schedules a target uplink transmission (transmission set as PUSCH 1) for terminal 1, and then needs to schedule another uplink transmission (transmission set as PUSCH 2) for terminal 2, where PUSCH2 and PUSCH1 overlap or partially overlap in frequency domain/time domain, the base station sends the downlink control signaling to terminal 1, and instructs the terminal to adjust the transmission power of PUSCH1 or cancel the scheduled transmission of PUSCH 1.

As an embodiment, the downlink control signaling includes an indication field;

When the downlink control signaling is a group common signaling, the indication field in the downlink control signaling may multiplex the existing field in the group common signaling, or use a newly added field, which is not limited specifically herein.

In summary, in the embodiments of the present invention, the network side device sends the downlink control signaling carrying the power adjustment instruction or the cancellation instruction to the terminal, and the terminal adjusts the transmission power of the target uplink transmission according to the power adjustment instruction or cancels the target uplink transmission according to the cancellation instruction, and this indication manner can flexibly indicate the power adjustment or cancellation of the terminal, and implement protection on terminal transmission, thereby improving communication skills.

In order to more clearly indicate the uplink transmission provided by the embodiment of the present invention, the following description is made with reference to two examples.

Example 1

Terminal a receives UL grant1 (e.g., DCI format 0_0 or DCI format 0_1) sent by the network side device at time n, and schedules a PUSCH1 transmitted at time n + k 1. The network side device schedules terminal B to transmit PUSCH2 at time n + k1 at time n + t1, (t1< ═ k1 and t1> 0). Wherein, the frequency domain resources of PUSCH1 and PUSCH2 are overlapped or partially overlapped, and the time domain resources of PUSCH1 and PUSCH2 are overlapped or partially overlapped.

After time n, the network side device may send a downlink control signaling (e.g., via UL grant 2) to the terminal a, where the downlink control signaling includes an indication field. The indication field may be an existing field in the UL grant for reuse or a field newly added. There are 2bits in this field, each of which may indicate 4 states, e.g., as indicated in Table 2.

Indication field	Means of
		00	Cancel indication, or transmit power equal to 0
01	Transmit power x1dB, or transmit power adjustment amplitude x2dB
		10	Indicating transmit power as y1dB or transmit power adjustment magnitude as y2dB
11	The transmission power is z1dB, or the transmission power is adjusted by z2dB

TABLE 2

The values of x1, x2, y1, y2, z1 and z2 can be configured by high layers and can be negative numbers, zero numbers or positive numbers; the unit may be a dB value or a linear value.

Example two

When the base station schedules the uplink transmission PUSCH3 of the eMBB terminal 1, the base station needs to schedule the uplink transmission PUSCH4 of the URLLC terminal 2, where the PUSCH4 and the PUSCH3 overlap or partially overlap in the frequency domain, the base station sends DCI 1 to the terminal 1, the indication field in the DCI 1 is 00(00 identifies cancellation indication, or identifies transmission power as 0), after the terminal 1 receives the DCI 1,

if terminal 1 has sufficient processing time, the terminal cancels the scheduled PUSCH 3. For example, the minimum processing time is N3, and the interval between the terminal 1 receiving the PDCCH carrying DCI 1 and the terminal starting to transmit PUSCH3 is L, where L is greater than or equal to N3.

If terminal 1 does not have sufficient processing time, the terminal ignores the indication of the indication field of the received DCI 1.

In summary, if the eMBB terminal and the URLLC terminal are dynamically multiplexed in the same resource pool, and when transmission of the eMBB service and transmission of the URLLC service overlap in the time domain/frequency domain, the network may flexibly instruct the eMBB terminal to adjust the transmission power or cancel transmission according to the time and resources for scheduling the eMBB and URLLC transmission, thereby implementing protection on the transmission of the URLLC terminal.

Preferably, in the above embodiments of the present invention, the correspondence between the indication state of the indication field and the power adjustment indication and/or the cancellation indication is predefined or configured by the network.
