Description
Technical Field
The present disclosure relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for processing downlink control information, an electronic device, and a storage medium.
Background
The 5G Mobile communication system supports both enhanced Mobile Broadband (eMBB) service And Ultra Reliable Low Latency Communication (URLLC) service. The typical eMBB service features large data transmission quantity, high transmission rate and insensitivity of data to transmission delay, and the typical URLLC service features ultrahigh transmission reliability, ultralow transmission delay, low transmission data quantity and burstiness and randomness.
According to URLLC traffic characteristics, a system will typically allocate symbol-level large bandwidth resources, while eMBB traffic will typically be allocated multiple slots of small bandwidth resources. When more eMBBs are transmitted, the system may not have idle resources to be allocated to the URLLC service in time, and the time delay performance of the URLLC service cannot be guaranteed. In order to meet the low delay characteristic of the URLLC service, the system allocates part of the downlink physical resources of the UE (User Equipment, User terminal) that have been allocated to the eMBB to the URLLC downlink service, that is, the URLLC downlink service data occupies the eMBB downlink service data, and in order to reduce the influence of URLLC downlink Preemption on the performance of the eMBB service, the system sends downlink PI (Preemption Indication) information at the next time slot to indicate that the UE of the eMBB is occupied with the physical resources.
Downlink PI information is sent to all UE by adopting a group sending mechanism, the UE adopts a nondifferential passive receiving mode to the Downlink PI information sent by the system, and all UE continuously monitors a Physical Downlink Control Channel (PDCCH) and demodulates the PDCCH to obtain the Downlink PI information belonging to the UE; and judging whether the physical resource of the previous time slot is preempted or not according to the downlink PI information. Because part of the UEs are not affected by resource preemption, unnecessary energy consumption is increased in the process of frequently monitoring and demodulating information, which is not beneficial to saving power of the terminal.

Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments that can be derived from the disclosure by one of ordinary skill in the art based on the embodiments in the disclosure are intended to be within the scope of the disclosure.
The disclosed embodiments provide a downlink control information processing method, apparatus, electronic device, computer-readable storage medium, and computer program product containing instructions to reduce unnecessary information demodulation of a user terminal, reduce energy consumption of the user terminal, and save electric energy of the user terminal.
Next, a downlink control information processing method provided in the embodiment of the present disclosure is first described. The method is applied to any electronic equipment which can provide the downlink control information processing service, such as a mobile phone, a tablet computer, a personal computer, a server and the like. The downlink control information processing method provided by the embodiment of the present disclosure may be implemented by at least one of software, a hardware circuit, and a logic circuit provided in the electronic device.
As shown in fig. 1, fig. 1 is a schematic flow chart of a downlink control information processing method provided in the embodiment of the present disclosure, and is applied to a user terminal, where the method includes:
s110, under the condition of a non-downlink aggregation time slot transmission mode, responding to downlink control information received in the current time slot, and acquiring data characteristics of first time slot data of the user terminal; wherein, the non-downlink aggregation time slot transmission mode is as follows: one downlink data is transmitted through only one time slot; the downlink preemption indication information in the downlink control information received in the current time slot is used for indicating: the information that the downlink data received by the user terminal in the first time slot is preempted;
s120, determining whether to demodulate the downlink preemption indication information in the downlink control information based on the data characteristics of the ue;
and S130, if not, not demodulating the downlink preemption indication information in the downlink control information.
When data is transmitted, the mode can be divided into a non-downlink aggregation time slot transmission mode and a downlink aggregation time slot transmission mode, wherein the non-downlink aggregation time slot transmission mode refers to that one to-be-transmitted data is transmitted only through one time slot and is not transmitted by adopting a plurality of different redundancy versions, and the downlink aggregation time slot transmission mode refers to that a plurality of redundancy versions of one downlink data are transmitted on a plurality of continuous time slots, so that the reliability of data transmission is improved.
The transmission mode of the user terminal can be determined according to a pre-configured mode configuration parameter, when the mode configuration parameter of the user terminal is configured as n and n is greater than 1, the data to be transmitted is represented by adopting 2 redundancy versions to be transmitted on n continuous time slots, and when n is equal to 1, the data to be transmitted is represented by adopting a non-downlink aggregation time slot transmission mode to be transmitted.
In addition, for the downlink data transmitted in each timeslot, if the data is preempted, the downlink preemption indication information is sent to all the user terminals in other timeslots after the preemption occurs, specifically, a number of timeslots may be preset after the downlink data is sent, for example, the next timeslot for sending the downlink data may be the next timeslot for sending the downlink data, and the next 2 timeslots for sending the downlink data may also be the next timeslot for sending the downlink data. For example, if downlink data is sent in the nth time slot, downlink preemption indication information is sent in the (n + 2) th time slot, which indicates that the downlink preemption indication information is the next 2 time slots in which the downlink data is sent, that is, downlink control information received in the (n + 2) th time slot characterizes downlink control information of the downlink data sent in the nth time slot, and the downlink preemption indication information characterizes preemption indication information of the downlink data sent in the nth time slot.
As shown in fig. 2, the transmission of the downlink data of the eMBB service data (eMBB UE1) of the user terminal 1 and the transmission of the downlink data of the eMBB service data (eMBB UE2) of the user terminal 2 have already started, and at this time, no idle resources are available for the incoming URLLC service, and in order to meet the low latency characteristics of the URLLC service, it is necessary to allocate part of the downlink physical resources allocated to the eMBB UE1 and the eMBB UE2 to the URLLC downlink service, that is, the URLLC downlink service data occupies the eMBB downlink service data, and in order to reduce the influence of the URLLC downlink preemption on the performance of the eMBB service, URLLC control information (downlink control information) is sent in the next timeslot, where the downlink control information includes downlink preemption indication information for indicating the physical resources occupied by the eMBB service data of the user terminal.
In order to reduce unnecessary information demodulation of the user terminal, reduce the energy consumption of the user terminal and save the electric energy of the user terminal. Under the condition of a non-downlink aggregation time slot transmission mode, when downlink control information is received, acquiring data characteristics of data corresponding to the downlink control information, wherein the data characteristics comprise data demodulation characteristics, data transmission characteristics, data feedback characteristics and data quality control information characteristics, judging whether to demodulate downlink preemption indication information in the downlink control information based on the data characteristics, if not, not demodulating the downlink preemption indication information in the downlink control information, and further, if it is judged that the downlink preemption indication information in the downlink control information needs to be demodulated based on the data characteristics of a user terminal, demodulating the downlink preemption indication information in the downlink control information. For clarity of the scheme and clarity of layout, the following detailed description is made with reference to another embodiment.
By combining the data characteristics of the user terminal, the processing mode of demodulating the downlink preemption indication information in the downlink control information is optimized on the premise of ensuring that the service performance of the user terminal is not influenced, and unnecessary information demodulation of the user terminal is reduced, so that the energy consumption of the terminal is reduced, and the power saving of the user terminal is facilitated.
In one possible embodiment, the data feature includes: data demodulation characteristics, data transmission characteristics, data feedback characteristics and data quality control information characteristics;
the determining, based on the data characteristics of the user terminal, whether to demodulate the downlink preemption indication information in the downlink control information includes:
when the data characteristics of the user terminal meet preset conditions, judging not to demodulate the downlink preemption indication information in the downlink control information;
when the data characteristics of the user terminal meet preset conditions, the downlink preemption indication information in the downlink control information is judged to be demodulated;
the preset condition includes at least one of the following conditions:
if the data demodulation characteristics indicate that the user terminal successfully demodulates the downlink data received in the first time slot; if the data transmission characteristics represent that the user terminal does not receive downlink data in the first time slot;
if the data feedback characteristic represents that the user terminal feeds back a confirmation message for representing correct demodulation of data aiming at the downlink data received in the first time slot;
and if the data quality control information represents that the service characteristic of the user terminal is a low-delay service.
The downlink preemption indication information for each downlink data may be scrambled by INT-RNTI (inter arrival Radio Network temporary Identity, discontinuous Radio Network temporary Identity), and a DCI 2_1 format is adopted on the PDCCH.
The DCI 2_1 transmission period is configured by higher layer parameters, i.e., all the user terminals to which other slots are transmitted after preemption occurs. The number of time slots may be preset after the downlink data is transmitted, for example, the next time slot for transmitting the downlink data may be set, or the next 2 time slots for transmitting the downlink data may be set.
For each time slot, after the user terminal receives the downlink data transmitted by each time slot, the user terminal may generate data characteristics of the downlink data received by the time slot, where the data characteristics include data demodulation characteristics, data transmission characteristics, data feedback characteristics, and the like, and specifically, the data characteristics of the downlink data of each time slot may be stored locally in the user terminal, and specifically, a correspondence table between the downlink data, the time slot for transmitting the downlink data, the downlink control information corresponding to the downlink data, and the time slot for transmitting the downlink control information may be established.
The data demodulation feature is used for representing the demodulation condition of the user terminal on the received downlink data, and specifically includes that the downlink data received in the corresponding time slot is successfully demodulated, or the downlink data received in the corresponding time slot is not successfully demodulated; for each time slot, when the data demodulation characteristics indicate that the user terminal successfully demodulates the downlink data received in the time slot, and the user terminal receives the downlink control information corresponding to the time slot, the user terminal does not try to demodulate the downlink preemption indication information in the downlink control information corresponding to the time slot.
The data transmission characteristics are used for representing whether the user terminal receives downlink data aiming at each time slot or not; the data feedback feature represents Acknowledgement information for correctly demodulating feedback characterization data of downlink data received in a time slot by a user terminal, that is, if the user terminal is directed at a certain time slot, the user terminal receives the downlink data in the time slot and correctly demodulates the downlink data, the user terminal feeds back an Acknowledgement information, for example, ACK (Acknowledgement character) information, and after the user terminal feeds back the ACK information, it indicates that the user terminal has received the downlink time slot transmitted in the time slot, and then it is not necessary to demodulate downlink preemption indication information.
The data quality control information represents the service characteristics of the user terminal, and only the URLLC service occupies the downlink eMBB service, so that the downlink data is not occupied when the service characteristics of the user terminal are low-delay services, and demodulation of the downlink occupation indication information therein is not required even if the downlink control information corresponding to the downlink data is received.
In one possible embodiment, the method includes:
under the condition of a downlink aggregation time slot transmission mode, under the condition of the downlink aggregation time slot transmission mode and under the condition that downlink control information is received in a current time slot, judging whether the current time slot is a corresponding redundancy period of downlink data corresponding to the downlink control information; wherein, the transmission mode of the downlink aggregation time slot is as follows: respectively transmitting a plurality of redundancy versions of downlink data through each time slot of a redundancy cycle, wherein one redundancy cycle comprises a plurality of time slots;
if not, acquiring the data characteristics of the user terminal in the redundancy period; judging whether to demodulate the downlink preemption indication information in the downlink control information or not based on the data characteristics of the user terminal in the redundancy period;
and if so, storing the downlink control information.
When in a downlink aggregation timeslot transmission mode, if downlink control information is received in a current timeslot, it needs to be determined whether the current timeslot is a redundancy cycle corresponding to downlink data corresponding to the downlink control information, if not, it is determined whether multiple redundancy versions of each timeslot in the redundancy cycle of the downlink data corresponding to the downlink control information have been transmitted, it needs to obtain data characteristics of the downlink data transmitted in each timeslot in the redundancy cycle, specifically, the data characteristics include a data demodulation characteristic, a data transmission characteristic, a data feedback characteristic, and a data quality control information characteristic, it is determined whether to demodulate downlink preemption indication information in the downlink control information based on data characteristics of a user terminal in the redundancy cycle, and if the timeslot is in the redundancy cycle, the downlink preemption indication information in the downlink control information is not demodulated temporarily, and the downlink control information is stored, so that whether demodulation is performed or not is judged after all redundancy versions of the redundancy period are sent.
In a possible embodiment, the determining whether to demodulate the downlink preemption indication information in each downlink control information based on the data characteristics of the user terminal in the redundancy cycle includes:
if the downlink data received in at least one time slot is successfully demodulated; or
If the user terminal feeds back a confirmation message for representing correct demodulation of the data aiming at least downlink data received in one time slot; or
If the service characteristic of the user terminal is low-delay service.
Because the downlink data transmits a plurality of redundancy versions in a redundancy period, if the downlink data received in at least one time slot is successfully demodulated, the downlink data is indicated to be successfully demodulated, even if the downlink control information corresponding to the downlink data transmitted in the redundancy period is received, the downlink preemption indication information in the downlink control information is not required to be demodulated, or the user terminal feeds back a confirmation message for representing the correct demodulation of the data for the downlink data received in at least one time slot, the data is indicated to be successfully demodulated, even if the downlink control information corresponding to the downlink data transmitted in the redundancy period is received, the downlink preemption indication information in the downlink control information is not required to be demodulated, or the service characteristic of the user terminal is a low-delay service, the downlink data of the low-delay service is not required to be preempted, therefore, even if the downlink control information corresponding to the downlink data is received, the downlink preemption indication information does not need to be demodulated.
As shown in fig. 3, the eMBB UE1 transmits in a downlink aggregation timeslot transmission mode from timeslot n to timeslot n +7, where the aggregation level is 8, that is, multiple redundancy versions of downlink data are transmitted through consecutive 8 timeslots; downlink preemption occurs in a time slot n and a time slot n +1, downlink preemption indication PI information of the time slot n +1 and the time slot n +2 respectively indicates preemption positions in the time slot n and the time slot n +1, and when a user terminal monitors a PDCCH in the time period from the time slot n +1 to the time slot n +7, even if URLLC control information (downlink control information) is received, the downlink preemption indication PI information is not demodulated temporarily, but whether the downlink preemption indication information in the downlink control information received in the time period from the time slot n +1 to the time slot n +7 is demodulated is determined based on the data characteristics of each data after all downlink data on the time slot n and the time slot n +7 are received.
Specifically, when the downlink data between the time slot n and the time slot n +7 is transmitted, and if it is determined that the downlink data received in at least one time slot between the time slot n and the time slot n +7 has been successfully demodulated, even if the downlink control information is received in the time slot n +1 and the time slot n +8, the downlink preemption indication information in the downlink control information received in the time slot n +1 and the time slot n +8 does not need to be demodulated.
Or, if the user terminal feeds back a confirmation message indicating that the data is correctly demodulated for the downlink data received in at least one timeslot, even if the downlink control information is received in the timeslot n +1 and the timeslot n +8, the downlink preemption indication information in the downlink control information received in the timeslot n +1 and the timeslot n +8 does not need to be demodulated.
Or, if the service characteristic of the user terminal is a low-latency service, it is not necessary to demodulate the downlink preemption indication information in the downlink control information received in each timeslot.
