This disclosure relates to the field of wireless communication technology, and in particular, to a method for information processing, a user equipment (UE), and a network device.
Currently, in order to reduce power consumption of a user equipment (UE), a low-power receiving technology is introduced in a wireless communication system. In the low-power receiving technology, the UE is provided with an ultra-low power wake-up receiver and a main radio. When the UE is in a normal receiving state, the main radio operates normally. When the UE is in a low-power receiving state, the main radio enters an off or deep sleep state, and the ultra-low power wake-up receiver operates normally. In general, the UE in the normal receiving state can enter the low-power receiving state after receiving an indication from a network side. The UE in the low-power receiving state can enter the normal receiving state after receiving a wake-up signal from the network side.
However, at present, the switch of the UE from the normal receiving state to the low-power receiving state has a problem of low flexibility.
In a first aspect, a method for information processing is provided in embodiments of the disclosure. The method includes the following. After receiving target indication information from a network side, a user equipment (UE) determines, according to a transmitting/receiving state of the UE, whether to respond to the target indication information. The target indication information indicates the UE to enter a low-power receiving state.
In a second aspect, a user equipment (UE) is provided in embodiments of the disclosure. The UE includes: a transceiver, a memory configured to store computer programs, and a processor configured to execute the computer programs stored in the memory to: determine, according to a transmitting/receiving state of the UE, whether to respond to target indication information, after receiving the target indication information from a network side. The target indication information indicates the UE to enter a low-power receiving state.
In a third aspect, a network device is provided in embodiments of the disclosure. The network device includes: a transceiver, a memory configured to store computer programs, and a processor configured to execute the computer programs stored in the memory to cause the transceiver to: transmit target indication information to a user equipment (UE). The target indication information is used by the UE for determining, according to a transmitting/receiving state of the UE, whether to respond to the target indication information. The target indication information indicates the UE to enter a low-power receiving state.
In order to make the objectives, technical solutions, and advantages of the disclosure clearer, the disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It may be understood that, the embodiments described herein are merely intended for explaining the disclosure rather than limiting the disclosure.
Currently, a low-power receiving technology is introduced in a wireless communication system. Reference is made to
As illustrated in
Currently, as long as the UE in the normal receiving state receives the indication information from the network side, the UE enters the low-power receiving state according to the indication from the network side. However, such a manner has low flexibility.
In view of this, a method and apparatus for information processing, a device, and a storage medium are provided in embodiments of the disclosure. In this method for information processing, after receiving target indication information from the network side, the UE can determine, according to a transmitting/receiving state of the UE, whether to respond to the target indication information. The target indication information indicates the UE to enter the low-power receiving state. In this way, the UE can flexibly determine, according to the transmitting/receiving state of the UE, whether to enter the low-power receiving state in response to the indication from the network side. Therefore, the flexibility of the switch of the UE from the normal receiving state to the low-power receiving state can be improved.
Reference is made to
At 301, after receiving target indication information from a network side, a UE determines, according to a transmitting/receiving state of the UE, whether to respond to the target indication information. The target indication information indicates the UE to enter a low-power receiving state.
Currently, when the UE is in a normal receiving state, the network side can predict requirements of the UE for data transmission in a period of time in the future. If the network side predicts that the UE has no requirement for data transmission in a period of time in the future, the network side can deliver the target indication information to the UE. As long as the UE receives the target indication information, the UE enters the low-power receiving state according to the indication from the network side.
However, in actual application, the network side may not accurately predict requirements of the UE for data transmission in a period of time in the future. In a case where the UE has requirements for transmission, if the UE enters the low-power receiving state according to the indication from the network side, normal operation of the UE will be affected.
For example, in some scenarios, the UE may trigger an uplink transmission and thus expect a further response from the network side. From the perspective of the network side, only after receiving data of the uplink transmission triggered by the UE, the network side can know that the UE has requirements for data transmission. Before receiving data of the uplink transmission triggered by the UE, the network side cannot know that the UE has requirements for data transmission. In this case, the network side may mispredict that the UE has no requirement for data transmission in a period of time in the future, thereby indicating the UE to enter the low-power receiving state. In this case, if the UE enters the low-power receiving state according to the indication from the network side, normal operation of the UE will be affected.
In view of this, in embodiments of the disclosure, after receiving the target indication information from the network side, the UE can determine, according to the transmitting/receiving state of the UE, whether to respond to the target indication information. In this way, the UE can be prevented from blindly entering the low-power receiving state according to the indication from the network side, thereby ensuring normal operation of the UE.
In an optional embodiment of the disclosure, if the UE has triggered an uplink transmission and there is no response from the network side to the triggered uplink transmission, it means that the UE has requirements for data transmission in a period of time in the future. In this case, the UE may ignore the target indication information, do not respond to the target indication information, and remain in the normal receiving state.
In addition, if the UE has not triggered an uplink transmission, it means that the prediction of requirements of the UE for data transmission in a period of time in the future by the network side may be accurate. In this case, the UE can respond to the target indication information, so as to enter a low-power receiving state.
If the UE has triggered an uplink transmission and there is a response from the network side to the triggered uplink transmission, it means that the UE currently has no requirement for monitoring a downlink channel and receiving downlink data. In this case, the prediction of requirements of the UE for data transmission in a period of time in the future by the network side may also be accurate. In this case, the UE can respond to the target indication information, so as to enter the low-power receiving state.
Three typical cases in which “the UE has triggered an uplink transmission and there is no response from the network side to the triggered uplink transmission” are provided in embodiments of the disclosure. It may be noted that, these three cases are merely exemplary. In actual application, all UE transmitting/receiving cases satisfying the condition that “the UE has triggered an uplink transmission and there is no response from the network side to the triggered uplink transmission” may be included in the scope of protection of the disclosure.
In a first case, the UE has triggered an uplink transmission of a scheduling request (SR) and the triggered uplink transmission of the SR is in a pending state.
It may be noted that, the UE involved in the first case is a UE in a radio resource control (RRC) connected state.
The SR is short for the scheduling request, which represents an uplink scheduling request. Generally, when the UE has requirements for uplink data transmission and has no physical uplink shared channel (PUSCH) communication resource available for uplink transmission, the UE can transmit the SR to the network side, so as to indicate the network side to allocate an uplink resource to the UE.
In general, since the network side cannot determine when the UE has requirements for uplink data transmission, the network side cannot determine when the UE triggers the uplink transmission of the SR. Therefore, in a case where the UE has triggered the uplink transmission of the SR but the network side has not received the SR from the UE, the network side may mispredict that the UE has no requirement for data transmission in a period of time in the future, and indicate, according to the prediction, the UE to enter the low-power receiving state.
In consideration of the above case, when the UE has triggered the uplink transmission of the SR and the triggered uplink transmission of the SR is in the pending state (that is, there is no response from the network side to the triggered uplink transmission of the SR), the UE can ignore the target indication information delivered by the network side, thereby ensuring that the UE can be maintained in the normal receiving state.
The pending state of the uplink transmission of the SR includes: a state in which the SR is not transmitted to the network side on an uplink communication resource; and/or a state in which the SR is transmitted to the network side on an uplink communication resource and no response information for the SR is received from the network side.
Generally speaking, the UE can transmit the SR on an uplink communication resource in a physical uplink control channel (PUCCH). In actual application, a case where the UE has triggered the uplink transmission of the SR but the UE still needs to wait for a PUCCH uplink communication resource for transmission of the SR may occur. In this case, the uplink transmission of the SR is in the pending state, i.e., the state in which the SR is not transmitted to the network side on the uplink communication resource. In addition, in actual application, in a case where the SR is transmitted by the UE on the PUCCH uplink communication resource, the network side usually can receive and respond to the SR only after a period of time. Within this period of time, the uplink transmission of the SR is in the pending state, i.e., the state in which the SR is transmitted to the network side on the uplink communication resource and no response information for the SR is received from the network side.
In order to facilitate the understanding of the technical solutions involved in the first case, reference is made to
In a second case, the UE is in a random access procedure.
It may be noted that, the random access procedure involved in the second case may be a contention based random access (CBRA) procedure or a contention free random access (CFRA) procedure. The UE involved in the second case may be a UE in an RRC connected state, a UE in an RRC idle state, or a UE in an RRC inactive state.
In some scenarios, the random access procedure is triggered by the UE. Therefore, before receiving a random access message from the UE, the network side may not know that the UE has triggered the random access procedure. In this case, the network side may mispredict that the UE has no requirement for data transmission in a period of time in the future, and indicate, according to the prediction, the UE to enter the low-power receiving state.
In consideration of the above case, when the UE is in the random access procedure, the UE can ignore the target indication information delivered by the network side, thereby ensuring that the UE can be maintained in the normal receiving state.
The UE being in the random access procedure may include the following.
1. The UE has triggered a random access and has not transmitted random access message 1 or random access message A to the network side on an uplink communication resource.
2. The UE has triggered a random access and has not received random access message 2 or random access message B from the network side.
Generally speaking, the random access may include a four-step random access and a two-step random access. During the four-step random access, the UE transmits the random access message 1 to the network side, the network side transmits the random access message 2 to the UE based on the random access message 1, the UE transmits random access message 3 to the network side based on the random access message 2, and the network side transmits random access message 4 to the UE based on the random access message 3. In this way, the random access procedure is completed. During the two-step random access, the UE transmits the random access message A to the network side, and the network side transmits the random access message B to the UE based on the random access message A. In this way, the random access procedure is completed.
If the UE has triggered the random access but has not transmitted the random access message 1 or the random access message A to the network side on the uplink communication resource (for example, the UE is waiting for an uplink communication resource available for transmitting the random access message 1 or the random access message A), the network side may not know that the UE has triggered the random access. In this case, the network side may mispredict that the UE has no requirement for data transmission in a period of time in the future, and indicate, according to the prediction, the UE to enter the low-power receiving state. In consideration of this, the UE may ignore the target indication information delivered by the network side, thereby ensuring that the UE can be maintained in the normal receiving state.
In addition, if the UE has triggered the random access but has not received the random access message 2 or the random access message B from the network side, the network side may have not received the random access message 1 or the random access message A transmitted by the UE. In this case, the network side may not know that the UE has triggered the random access. As a result, the network side may mispredict that the UE has no requirement for data transmission in a period of time in the future, and indicate, according to the prediction, the UE to enter the low-power receiving state. In consideration of this, the UE may ignore the target indication information delivered by the network side, thereby ensuring that the UE can be maintained in the normal receiving state.
In order to facilitate the understanding of the technical solutions involved in the second case, reference is made to
In a third case, the UE has triggered an uplink transmission of a buffer status report (BSR) and the BSR is in an un-cancelled state.
It may be noted that, the UE involved in the third case is a UE in an RRC connected state.
The BSR is short for the buffer status report, which represents a report of buffer status. Generally, when the UE has requirements for uplink data transmission, the UE can transmit the BSR to the network side, so as to inform the network side of a data volume of uplink data to be transmitted by the UE. In this way, the network side can allocate to the UE an uplink resource necessary for transmission of the uplink data based on the data volume reported by the UE.
In general, the network side cannot determine when the UE triggers the uplink transmission of the BSR. Therefore, in a case where the UE has triggered the uplink transmission of the BSR but the network side has not received the BSR from the UE, the network side may mispredict that the UE has no requirement for data transmission in a period of time in the future, and indicate, according to the prediction, the UE to enter the low-power receiving state.
In consideration of the above case, when the UE has triggered the uplink transmission of the BSR and the BSR is in the un-cancelled state (that is, there is no response from the network side to the BSR), the UE can ignore the target indication information delivered by the network side, thereby ensuring that the UE can be maintained in the normal receiving state.
The un-cancelled state of the BSR includes: a state in which the BSR is not transmitted to the network side on an uplink communication resource; and/or a state in which the BSR is transmitted to the network side on an uplink communication resource and no response information for the BSR is received from the network side.
Generally speaking, the UE can transmit the BSR on an uplink communication resource in a PUSCH. In actual application, a case where the UE has triggered the uplink transmission of the BSR but the UE still needs to wait for a PUSCH uplink communication resource for transmission of the BSR may occur. In this case, the BSR is in the un-cancelled state, i.e., the state in which the BSR is not transmitted to the network side on the uplink communication resource. In addition, in actual application, in a case where the BSR is transmitted by the UE on the PUSCH uplink communication resource, the network side usually can receive and respond to the BSR only after a period of time. Within this period of time, the BSR is in the un-cancelled state, i.e., a state in which the SR is transmitted to the network side on the uplink communication resource, the BSR is transmitted to the network side on the uplink communication resource, and no response information for the BSR is received from the network side.
In order to facilitate the understanding of the technical solutions involved in the third case, reference is made to
Based on technical solutions provided in embodiments of the disclosure, after receiving the target indication information from the network side, the UE can determine, according to the transmitting/receiving state of the UE, whether to respond to the target indication information. The target indication information indicates the UE to enter the low-power receiving state. In this way, the UE can flexibly determine, according to the transmitting/receiving state of the UE, whether to enter the low-power receiving state in response to an indication from the network side. Therefore, the flexibility of the switch of the UE from the normal receiving state to the low-power receiving state can be improved, and both low power consumption of the UE and quality of service (QOS) of communication services in the UE can be taken into account.
