Description

Data transmission method and equipment
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method and a device for data transmission.
Background
With the continuous development of communication technology, in the process of wireless communication, more and more attention is paid to reducing power consumption of a terminal, wherein in order to reduce power consumption of the terminal and better save power of the terminal in the process of wireless communication, DRX (Discontinuous Reception) is introduced, that is, the terminal periodically enters a sleep state, does not listen to a PDCCH (Physical Downlink Control Channel), periodically enters an active state, and listens to a PDCCH Channel, thereby reducing power consumption of the terminal and saving power.
However, in the wireless communication process, a timer is often used to trigger task execution, timing, etc., such as a DRX HARQ (Hybrid Automatic Repeat reQuest) RTT (Round trip time) timer and a retransmission timer. In the application process, after the HARQ RTT timer expires, the UE opens the retransmission timer, and when the retransmission timer runs, the network side may send retransmission scheduling information to the terminal, so that the terminal may listen to the PDCCH channel, and conflict with the energy saving signal, so that the energy saving effect cannot be achieved.
In summary, the success rate of performing the energy saving operation according to the energy saving signal in the wireless communication process is low.
Disclosure of Invention
The embodiment of the invention provides a data transmission method and equipment, which are used for solving the problem that the success rate of energy-saving operation according to an energy-saving signal is low in the process of wireless communication at present.
In a first aspect, a method for data transmission provided in an embodiment of the present invention includes:
after receiving an energy-saving signal sent by network side equipment in a DRX state, a terminal executes energy-saving operation according to the energy-saving signal and determines whether a first timer is running at present; and if the terminal determines that the current first timer is running, the terminal closes the first timer.
According to the method, after the terminal receives the energy-saving signal, when the energy-saving operation is executed according to the energy-saving signal, if the first timer is determined to be running currently, the terminal closes the first timer, so that interference conflict generated on the energy-saving signal due to the running of the first timer is effectively reduced, the energy-saving effect is better realized, and the success rate of the energy-saving operation is improved.
In one possible implementation manner, the terminal performs an energy saving operation according to the energy saving signal, including: the terminal stops monitoring the PDCCH in L PDCCH monitoring time slots; or if the terminal needs to enter a DRX activation state according to the indication of the network side, the terminal enters a DRX idle state from a DRX connection state at the next DRX activation moment; if the terminal does not need to enter a DRX activation state according to the indication of the network side, the terminal keeps a DRX idle state at the next DRX activation moment; or the terminal keeps DRX idle inactive.
The above-mentioned methods respectively introduce the energy-saving operations determined according to the energy-saving signals in the embodiments of the present invention, where the energy-saving operations executed after receiving the energy-saving signals are different according to different energy-saving configurations of the terminal, for example, the energy-saving operations executed according to the energy-saving signals stop monitoring the PDCCH at L PDCCH monitoring time slots for the terminal, or the terminal enters a DRX idle state from a DRX connected state, or the terminal maintains the DRX idle state.
In a possible implementation, the first timer is a DL DRX HARQ RTT timer or an UL DRXHARQ RTT timer or a DL DRX retransmission timer or an UL DRX retransmission timer.
In the method, when the first timer is the timer, the first timer is likely to affect the executed energy saving operation during the starting or running period of the first timer, so the first timer in the embodiment of the invention is a DL DRX HARQ RTT timer or an UL DRX HARQ RTT timer or a DL DRX retransmission timer or an UL DRX retransmission timer.
In a possible implementation manner, after stopping monitoring the PDCCH in L PDCCH monitoring slots and before turning off the first timer, the terminal further includes: and the terminal determines that the duration of the L PDCCH interception time slots is less than the duration of a first timer.
According to the method, the first timer is closed when the terminal determines that the duration of the L PDCCH interception time slots is shorter than the duration of the first timer, so that the times of closing the timer is better reduced, the operation is saved, and the power consumption is reduced.
In a possible implementation manner, after the terminal receives a power saving signal sent by a network side device in a DRX state, the method further includes: and if the terminal sends a scheduling request SR to network side equipment or executes a random access process, the terminal ignores the energy-saving operation indicated by the energy-saving signal.
In the method, when the terminal performs the random access procedure or sends the scheduling Request while waiting for the network-side scheduling procedure, if the terminal continues to execute the energy saving operation, the execution of the random access procedure or the scheduling procedure may be affected, so in the embodiment of the present invention, if the terminal sends an SR (scheduling Request) to the network-side device or executes the random access procedure, the terminal ignores the energy saving operation indicated by the energy saving signal.
In a second aspect, an embodiment of the present invention provides a device for data transmission, including: a processor, a memory, and a transceiver:
the processor is used for executing energy-saving operation according to the energy-saving signal after the DRX state receives the energy-saving signal sent by the network side equipment, and determining whether a first timer is running at present; and if the first timer is determined to be running currently, closing the first timer.
In a third aspect, an embodiment of the present invention further provides a device for data transmission, where the device includes:
at least one processing unit and at least one memory unit, wherein the memory unit has stored program code which, when executed by the processing unit, causes the processing unit to perform the functions of the embodiments of any of the above-mentioned first aspects.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without any creative efforts shall fall within the protection scope of the embodiments of the present invention.
Some of the words that appear in the text are explained below:
(1) In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.
(2) "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
(3) In the embodiment of the application, after the 'DRX HARQ RTT timer' is overtime, a DRX retransmission timer is operated, wherein the DRX HARQ RTT timer is divided into a DL DRX HARQ RTT timer and a UL DRX HARQ RTT timer.
(4) In the embodiment of the present application, during the "DRX retransmission timer" operation period, the UE monitors the PDCCH, wherein the DRX retransmission timer is divided into a DL DRX retransmission timer and a UL DRX retransmission timer.
(5) In the embodiment of the present application, "DRX connected state" means that the UE will monitor the PDCCH channel.
(6) In the embodiment of the present application, "DRX idle state" means that the UE will stop listening to the PDCCH channel.
In the embodiment of the present invention, when the terminal enters the DRX state, there are two different states, namely a DRX connected state and a DRX idle state, where as shown in fig. 1, the period of time labeled "Duration On Duration" represents the DRX connected state, that is, the time when the UE monitors the downlink PDCCH subframe, and at this time, the UE is in an awake state, and power consumption is relatively high. The period of time identified as "Opportunity for DRX" represents a DRX idle state, i.e., the time when the UE does not monitor PDCCH subframes, and at this time, the UE is in a dormant state, and power consumption is relatively low.
In the data transmission process, in order to reduce power consumption of the terminal and save electric quantity, the embodiment of the invention receives an energy-saving signal sent by a network side.
As shown in fig. 2, an embodiment of the present invention provides a method for data transmission, where the method includes:
step 200, after receiving an energy-saving signal sent by a network side device in a DRX state, a terminal executes energy-saving operation according to the energy-saving signal and determines whether a first timer is running at present.
Step 201, if the terminal determines that the current first timer is running, the terminal closes the first timer.
According to the method, after the terminal receives the energy-saving signal, when the energy-saving operation is executed according to the energy-saving signal, if the first timer is determined to be running currently, the terminal closes the first timer, so that interference conflict generated on the energy-saving signal due to the running of the first timer is effectively reduced, the energy-saving effect is better realized, and the success rate of the energy-saving operation is improved.
Further, in the embodiment of the present invention, before entering the DRX state, the network side DRX configuration and the energy saving configuration are received, so that after the terminal receives an energy saving signal sent by a network side device in the DRX state, an energy saving instruction indicated by the energy saving signal is determined according to the energy saving configuration, where the energy saving instruction is not specifically limited to the following.
Energy saving instruction 1: the UE enters a PDCCH skipping state.
Energy saving instruction 2: the UE enters a sleep state.
It should be noted that, in the embodiment of the present invention, the energy saving signal may be in a MAC CE (media access Control element) format or a DCI (Downlink Control Information) format, and any format of the energy saving signal suitable for the embodiment of the present invention may be used as the format of the energy saving signal in the embodiment of the present invention.
Further, after determining the energy saving instruction indicated by the energy saving signal, the terminal executes the energy saving instruction, and determines whether a first timer is running currently, wherein the first timer is a DL DRX HARQ RTT timer or an uplink UL DRX HARQ RTT timer or a DL DRX retransmission timer or an UL DRX retransmission timer.
Further, the energy saving operations executed by the terminal according to different energy saving instructions are also different, and are respectively described below, where as shown in fig. 3a, the DL operating state diagram when the terminal does not perform the energy saving operation according to the embodiment of the present invention, and as shown in fig. 3b, the UL operating state diagram when the terminal does not perform the energy saving operation according to the embodiment of the present invention.
Energy-saving operation 1: and if the energy-saving instruction is an energy-saving instruction 1, namely the UE enters a PDCCH skiping state, the terminal stops monitoring the PDCCH in L continuous PDCCH monitoring time slots. Wherein the parameter L is an integer greater than or equal to 1.
It should be noted that the parameter L may be preconfigured on the network side, or may be notified in the energy saving signal.
Further, when the energy saving instruction corresponding to the energy saving signal determined by the terminal in the embodiment of the present invention is the energy saving instruction 1, in order to avoid that the running process of the first timer in the embodiment of the present invention interferes with the execution of the energy saving operation, so that the energy saving operation cannot be executed smoothly, and the energy saving effect is achieved, therefore, the embodiment of the present invention further executes the closing operation on the first timer.
In the embodiment of the present invention, for different first timers, the influence of the energy saving signal on the first timer is different, and the following description is separately provided.
Case 1: assuming that, when the first timer is a DL DRX HARQ RTT timer, the terminal executes the energy saving operation as shown in fig. 4a, and when the terminal receives an energy saving signal and the terminal is currently in the running period of the DL DRX HARQ RTT timer, the terminal closes the DL DRX HARQ RTT timer and stops monitoring the PDCCH at L consecutive PDCCH monitoring time slots. Since DL DRX HARQ RTT is not timed out, DL DRX retransmission timer will not start.
Case 2: assuming that the first timer is a UL DRX HARQ RTT timer, the terminal executes the energy saving operation as shown in fig. 4b, and when the terminal receives an energy saving signal and the terminal is currently in the running period of the UL DRX HARQ RTT timer, the terminal closes the UL DRX HARQ RTT timer and stops monitoring PDCCH in L consecutive PDCCH monitoring time slots. Since the UL DRX HARQ RTT is not timed out, the UL DRX retransmission timer will not start.
Case 3: assuming that the first timer is a DL DRX retransmission timer, the schematic diagram of the terminal performing the energy saving operation is shown in fig. 5a, and when the terminal receives an energy saving signal and the terminal is currently in the period of operation of the DL DRX retransmission timer, the terminal closes the DL DRX retransmission timer and stops monitoring the PDCCH in L consecutive PDCCH monitoring time slots.
Case 4: assuming that the first timer is a UL DRX retransmission timer, the schematic diagram of the terminal performing the energy saving operation is shown in fig. 5b, and when the terminal receives an energy saving signal and the terminal is currently in the period of the UL DRX retransmission timer running, the terminal closes the UL DRX retransmission timer and stops monitoring the PDCCH in L consecutive PDCCH monitoring slots.
The DL DRX HARQ RTT timer or the UL DRX HARQ RTT timer does not interfere with the execution of the power saving operation during the operation period, and the DRX HARQ RTT timer is mainly prevented from being started to interfere with the power saving operation after the DRX HARQ RTT timer is overtime.
Optionally, if the current first timer is a DL DRX HARQ RTT timer or an UL DRX HARQ RTT timer, and the terminal determines that the duration of the L PDCCH listening slots is not less than the duration of the first timer, the terminal does not need to close the first timer.
That is, the terminal may determine whether to turn off the first timer when performing the power saving operation 1 according to the power saving signal by:
if the terminal determines that the duration of the L PDCCH interception time slots is less than the duration of a first timer, closing the first timer; or the like, or, alternatively,
and if the terminal determines that the duration of the L PDCCH interception time slots is not less than the duration of a first timer, and the first timer is a DRX retransmission timer, closing the first timer.
Further, the terminal continues to monitor the PDCCH after stopping monitoring the L PDCCH monitoring slots.
Energy-saving operation 2: if the energy-saving instruction is an energy-saving instruction 2, that is, the UE enters a sleep state, wherein if the terminal is in a DRX (discontinuous reception) connected state currently, the terminal enters a DRX idle state from the DRX connected state; or if the terminal is currently in the DRX idle state, the terminal continues to keep the DRX idle state.
Further, when the energy saving instruction corresponding to the energy saving signal determined by the terminal in the embodiment of the present invention is the energy saving instruction 2, in order to avoid that the running process of the first timer in the embodiment of the present invention interferes with the execution of the energy saving operation, so that the energy saving operation cannot be executed smoothly, and the energy saving effect is achieved, therefore, the embodiment of the present invention further executes the closing operation on the first timer.
Further, after receiving the wake-up command sent by the network side, the terminal enters a DRX connected state from a DRX idle state.
Optionally, in the embodiment of the present invention, if the terminal is executing a random access process after receiving the energy saving signal sent by the network side device, the terminal ignores the energy saving operation indicated by the energy saving signal.
For example, in the embodiment of the present invention, if a ra (Radio Access) -response window Timer is running or a ra-context Resolution Timer is running, it indicates that the terminal is executing a random Access procedure, and therefore, the terminal ignores the power saving operation indicated by the power saving signal. That is, after receiving the energy saving instruction, if the terminal device is executing the random access procedure, the stop operation of the first timer will not be executed according to the energy saving instruction.
Optionally, in the embodiment of the present invention, after receiving the energy saving signal sent by the network side device, the terminal sends the SR at this time, that is, the terminal waits for network side scheduling, and therefore, the terminal ignores the energy saving operation indicated by the energy saving signal. That is, after receiving the power saving instruction, if the terminal device has just transmitted the SR, the stop operation of the first timer is not performed according to the power saving instruction.
