Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for detecting a PDCCH.
Background
A New Radio (NR) design in the related art mainly aims at enhancing the wide coverage of an Enhanced Mobile Broadband (eMBB), the high rate requirement, and the Low Latency and high reliability characteristics of Ultra-Reliable and Low Latency Communication (URLLC), but the consideration for Low cost and large connection is relatively deficient. For more diversified terminal and usage scenarios in the future, such as sensor devices, wearable devices, and monitoring cameras, the bandwidth size (100MHz) and the number of transmit/receive antennas (4 transmit/receive 2) in the current NR protocol exceed the requirements of the terminal and the usage scenarios in this part, so in the future NR evolution direction, the lightweight NR is an important direction, the terminal type in the future is a low-cost and medium-level terminal, and the requirements for network performance indexes are lower than those of the terminal types in the current smart phones.
The terminal types supported by the lightweight NR are mainly sensor devices, wearable devices, monitoring cameras, and the like, and due to the reduction of the terminal capabilities (the number of receiving antennas, the maximum transmission power) of this part of terminals, the coverage capability of each physical channel becomes poor, and in order to compensate for the loss of coverage caused by the reduction of the terminal capabilities, the simplest way is to repeatedly transmit each physical channel, for example, one physical channel is repeatedly transmitted 2 times, which may bring about a coverage enhancement effect of about 3 dB.

The terminal types supported by the lightweight NR are mainly sensor devices, wearable devices, monitoring cameras, and the like, and in order to control cost and increase industrial development, the terminal capabilities and complexity thereof need to be smaller than those defined by the related art. For example, for a terminal supported by a lightweight NR, the supported bandwidth is smaller than the currently defined system bandwidth, the number of receiving antennas is reduced to 2 or 1, the number of supported Multiple Input Multiple Output (MIMO) streams is also reduced, and the maximum transmit power is also reduced. Meanwhile, in order to control the maintenance cost, the terminal supporting the lightweight NR has a more strict requirement on the terminal energy consumption, and the energy consumption of the terminal needs to be reduced as much as possible.
Due to the reduction of the terminal capability (number of receiving antennas, maximum transmission power) of this part of terminals, the coverage capability of each physical channel is deteriorated compared with the terminals supported by the related art, wherein the reduction of the number of antennas, for example, the reduction of the terminal from 2-transmission-4-reception to 1-transmission-2-reception, causes the coverage to shrink by 3 dB. In order to compensate for the loss of coverage due to the reduced terminal capability, the simplest way is to repeat the transmission of each physical channel, for example, one physical channel is repeated 2 times, which results in about 3dB coverage enhancement.
Currently, NR already supports repeated transmission of a Physical Downlink Shared Channel (PDSCH) and a Physical Uplink Shared Channel (PUSCH). The network side configures the number of times of repeated transmission N times (2 times, 4 times or 8 times) through a high-layer signaling, and indicates time-frequency domain resource allocation through Downlink Control Information (DCI), and the time-frequency domain resource allocation of each transmission is the same. The terminal performs repeated transmission of the PDSCH and/or the PUSCH on N consecutive slots, and if a certain slot does not satisfy the transmission condition (for example, when the PUSCH is repeatedly transmitted, the current slot is a downlink slot), the terminal ignores the transmission, but N continues to count. That is, the number of PUSCH actually transmitted by the terminal may be less than N.
For the terminal with the lightweight NR, due to the reduction of the number of the transmitting antennas and the maximum transmitting power thereof, and at the same time, due to the reduction of the antenna gain of the lightweight NR terminal, the penetration loss becomes large, the coverage of the uplink channel, e.g. PUSCH channel, may be reduced by about 10dB compared with the current NRPUSCH, and a manner of introducing a larger number of repeated transmissions (e.g. 16 times, 32 times, 64 times) is required to make up the coverage gap. However, in consideration of the requirement of terminal energy saving, repeated transmission of a physical channel may increase energy consumption of the terminal, especially in a usage scenario of lightweight NR, a traffic ratio of uplink data may be larger than that of a smartphone terminal, and in uplink energy consumption of the terminal, an energy consumption ratio occupied by a Power Amplifier (PA) is very high. Therefore, for the PUSCH uplink repeat transmission, if the network side has received the PUSCH transmitted by the terminal before configuring the number of repetitions to the terminal, the network side may notify the terminal to terminate the subsequent PUSCH repeat transmission by using a dynamic signaling, such as a Physical Downlink Control Channel (PDCCH), so that the invalid energy consumption overhead of the terminal is avoided.
However, frequent detection of the PDCCH terminating the uplink transmission may also cause extra detection overhead for the terminal, and therefore, the detection of the PDCCH instructing the terminal to terminate the uplink transmission in advance should be performed at certain intervals. The detection position of the PDCCH in the NR is determined by a detection period and a time length configured by a higher layer signaling, that is, the PDCCH is detected according to a certain period. But since the starting slot of the PUSCH repeated transmission is dynamically scheduled by DCI, and the PDCCH search space is semi-statically configured, its detection slot and the slot of the PUSCH transmission cannot necessarily match.
If the current configuration mode of the search space is not adopted, for example, the network side can predefine or configure the terminal to detect and terminate the uplink transmission PDCCH after transmitting the PUSCH for Y times, but the current repeated transmission mechanism of the PUSCH may cause some problems. The current repeated transmission of the PUSCH is on consecutive slots, and if a transmission slot that does not meet the condition is encountered, the transmission is skipped, so that a terminal may have a downlink slot for detecting the PDCCH after continuously transmitting more than Y times. In addition, because a Slot Format Indicator (SFI) is introduced into the NR, the slot format indicator may be used to dynamically change the uplink and downlink configuration of a slot or a symbol, so that the number of times of actual transmission and the slot need to be dynamically changed according to the current frame structure during the PUSCH retransmission process of the terminal, which may cause uncertainty in detecting the slot position of the PDCCH terminating the uplink transmission.
In order to solve the above problem, embodiments of the present invention provide a method and an apparatus for detecting a PDCCH, which can determine a detection position for terminating an uplink transmission PDCCH according to an actual time slot position of PUSCH transmission, so as to terminate subsequent repeated transmission of a PUSCH of a terminal in advance, and reduce energy consumption of the terminal.
An embodiment of the present invention provides a method for detecting a PDCCH, which is applied to a terminal, and as shown in fig. 1, the method includes:
step 101: acquiring a parameter for determining a detection position of a PDCCH terminating uplink transmission;
step 102: and detecting the PDCCH according to the detection position determined by the parameters, and terminating repeated transmission of the PUSCH after the PDCCH is detected.
In this embodiment, the terminal acquires a parameter for determining a detection position of a PDCCH for terminating uplink transmission, detects the PDCCH according to the detection position determined by the parameter, and terminates repeated transmission of a PUSCH after detecting the PDCCH. Through the technical scheme of the embodiment, the terminal can determine the detection position for terminating the PDCCH according to the actual time slot position of the PUSCH transmission, so that the terminal can terminate the subsequent repeated transmission of the PUSCH in advance, and the energy consumption of the terminal is reduced. The determination method of the PDCCH detection position in this embodiment may dynamically adapt to any frame structure and transmission time domain position of the PUSCH, and the detection position of the PDCCH may take the transmission number of the PUSCH of the terminal into account.
Optionally, the parameter comprises at least one of:
a first parameter, which is the repetition frequency or transmission frequency N of the PUSCH, or a parameter associated with N;
the length of time X.
Optionally, the obtaining of the parameter for determining the detection position of the PDCCH terminating the uplink transmission includes any one of:
acquiring the predefined parameters;
acquiring the parameters configured by the network side equipment through a high-level signaling;
and acquiring the parameters indicated by the network side equipment through the second downlink control information DCI.
Optionally, the PDCCH carries a first DCI, where the first DCI is used to instruct the terminal to stop transmitting the PUSCH.
Optionally, the first DCI adopts DCI format 0_1, where the first DCI is effective when the frequency domain resource allocation field and/or the frequency domain hopping indication field are set to any one of the following conditions:
if the terminal is only configured with the resource allocation type 0, the frequency domain resource allocation domain is all 0;
if the terminal is only configured with the resource allocation type 1 and the high-level signaling is not configured with the frequency domain hopping parameter, the frequency domain resource allocation domain is all 1;
if the terminal is only configured with the resource allocation type 1 and the high-level signaling is configured with the frequency domain hopping parameter, the frequency domain resource allocation domain is all 1 and the frequency domain hopping indication domain is 0;
if the terminal is configured with the resource allocation type 0 and the resource allocation type 1 and the high-level signaling is not configured with the frequency domain hopping parameter, the frequency domain resource allocation domain is all 0 or all 1;
if the terminal is configured with the resource allocation type 0 and the resource allocation type 1 and the high-level signaling is configured with the frequency domain hopping parameter, the frequency domain resource allocation domain is all 0 or the frequency domain resource allocation domain is all 1 and the frequency domain hopping indication domain is 0.
Optionally, the cyclic redundancy check, CRC, of the first DCI is scrambled by at least one of:
a cell radio network temporary identifier C-RNTI;
modulation and coding strategy MCS-C-RNTI;
CS-RNTI when new data in the DCI format indicates that the value of NDI is 1.
Optionally, the detecting the PDCCH at the detection position includes any one of:
after completing transmission of the PUSCH for N times, detecting the PDCCH in a time slot of a nearest detectable PDCCH after X time length of the Nth PUSCH transmission;
after completing transmission of the PUSCH at least N times, the PDCCH is detected in a slot of the nearest detectable PDCCH after X time length from the last PUSCH transmission.
Optionally, the starting position of the X time length is the last symbol or the slot where the nth PUSCH or the last PUSCH is transmitted or the next slot.
Optionally, counting is performed N times again after each detected position of the PDCCH or N times again after completing PUSCH transmission N times per transmission.
Where N represents that the terminal needs to detect the early termination signaling after N PUSCH transmissions or at least N PUSCH transmissions. Wherein different PUSCH repeated transmission times can be configured with different N values.
