Patent Description:
In a new radio (New Radio, NR) system, a physical downlink control channel (Physical Downlink Control Channel, PDCCH) is used to transmit downlink control information (Downlink Control Information, DCI). Normally, the number of DCI bits is greater than or equal to <NUM>. If the number of bits transmitted on the PDCCH is less than <NUM>, <NUM> need to be added to make the DCI <NUM> bits long before cyclic redundancy check (Cyclic Redundancy Check, CRC) bits are added (specifically, including CRC bits scrambled by using a radio network temporary identifier (Radio Network Temporary Identifier (RNTI)), and then polar (polar) coding is performed. The encoded bits are scrambled and modulated using quadrature phase shift keying (Quadrature Phase Shift Keying, QPSK) modulation to output a modulated symbol sequence, and the modulated symbol sequence is mapped to corresponding control channel element (Control Channel Element, CCE) resources for sending.

For reception of a PDCCH, a terminal needs to receive the PDCCH on CCE resources, including demodulating, decoding, descrambling, and performing a CRC check on the symbol sequence of the PDCCH. If the CRC check succeeds, the terminal considers that a PDCCH is detected. Therefore, in the related art, complexity of PDCCH reception is high, resulting in high power consumption of the terminal in monitoring.

<CIT> provides a method of two-stage scheduling in downlink control channel to enhance DCI forward compatibility and hardware flexibility. The DCI includes a basic DCI and an extended DCI. The basic DCI provides basic scheduling information of the scheduled data. The extended DCI provides extended scheduling information of the scheduled data channel. The basic DCI can be unicast to a single UE over UE-specific search space. The basic DCI can also be broadcast or multicast to a group of UEs over common search space. UE performs blind detection of the basic DCI only, while the location and size of the extended DCI can be provided by the basic DCI or provided by a higher layer signaling.

Embodiments of the present disclosure provide transmission methods, network devices, and terminals to resolve a problem that high complexity of PDCCH reception causes high power consumption of the terminal in detection.

According to a fifth aspect, an embodiment of the present disclosure further provides a network device, including a memory, a processor, and a program stored in the memory and capable of running on the processor, where when the program is executed by the processor, the steps of the foregoing transmission method on the network device side are implemented.

According to a sixth aspect, an embodiment of the present disclosure further provides a terminal, including a memory, a processor, and a program stored in the memory and capable of running on the processor, where when the program is executed by the processor, the steps of the foregoing transmission method on the terminal side are implemented.

According to a seventh aspect, an embodiment of the present disclosure further provides a computer-readable storage medium, where the computer-readable storage medium stores a program, and when the program is executed by a processor, the steps of the foregoing transmission method on the network device side are implemented, or when the program is executed by a processor, the steps of the foregoing transmission method on the terminal side are implemented.

In the embodiments of the present disclosure, the network device sends the indication information, where the indication information indicates the bit information of the one or more bits to be monitored by the terminal, so that the terminal can learn the number of bits that need to be detected and the corresponding bit positions. Therefore, the terminal can use a detection algorithm with relatively low complexity to perform detection, thus avoiding complex detection processes of a conventional detection algorithm such as channel estimation, detection, and decoding. Therefore, the embodiments of the present disclosure can reduce complexity of PDCCH reception, thereby reducing power consumption in detection.

Specifically, the terms such as "an example" or "for example" are intended to present related concepts in a specific manner.

The following describes the embodiments of the present disclosure with reference to the accompanying drawings. A transmission method, a network device, and a terminal provided in the embodiments of the present disclosure may be applied to a wireless communications system. The wireless communications system may be a <NUM> system, or an evolved long term evolution (Evolved Long Term Evolution, eLTE) system, or a later evolved communications system.

<FIG> is a structural diagram of a network system to which an embodiment of the present disclosure may be applied. As shown in <FIG>, the network system includes a terminal <NUM> and a network device <NUM>. The terminal <NUM> may be a user terminal or another terminal-side device, for example, a mobile phone, a tablet personal computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (personal digital assistant, PDA for short), a mobile Internet device (Mobile Internet Device, MID), or a wearable device (Wearable Device). It should be noted that a specific type of the terminal <NUM> is not limited in this embodiment of the present disclosure. The network device <NUM> may be a <NUM> base station, or a base station of a later version, or a base station in another communications system, or is referred to as a NodeB, or an evolved NodeB, or a transmission and reception point (Transmission Reception Point, TRP), or an access point (Access Point, AP), or other terms in the art. As long as a same technical effect is achieved, the network device is not limited to a specific technical term. In addition, the network device <NUM> may be a master node (Master Node, MN) or a secondary node (Secondary Node, SN). It should be noted that the <NUM> base station is used merely as an example in this embodiment of the present disclosure, rather than limiting a specific type of the network device.

<FIG> is a flowchart of a transmission method according to an embodiment of the present disclosure. The method is applied to a network device.

Step <NUM>: Send indication information, where the indication information includes a first indication, the first indication is used to indicate bit information of one or more bits to be monitored by a terminal, and the one or more bits to be monitored is at least one bit of downlink control information (DCI) on a physical downlink control channel (PDCCH).

In this embodiment of the present disclosure, the network device may send the indication information in a plurality of manners. For example, in some optional embodiments, the indication information may be transmitted by using at least one of system information, radio resource control (Radio Resource Control, RRC) signaling, a medium access control-control element (Medium Access Control-Control Element, MAC-CE), and the PDCCH. Specifically, which manner is used to transmit the indication information may be prescribed. For example, one or more of the system information, the RRC signaling, the MAC-CE, and the PDCCH may be used to send the indication information.

In an NR system, the number of bits used to transmit the DCI on the PDCCH may be understood as the total number of bits of the DCI on the PDCCH, and the number of bits is generally greater than or equal to <NUM>. The number of bits to be monitored is related to information transmitted on the PDCCH. When there are few bits of information transmitted on the PDCCH, the number of bits to be monitored may be less than the total number of bits of the DCI on the PDCCH. For example, in some optional embodiments, the total number of bits of the DCI on the PDCCH is <NUM>, the number of bits to be monitored is <NUM>, and the other bits are all known bits.

In this embodiment of the present disclosure, the foregoing bit information includes positions of bits. Specifically, in some optional embodiments, the number of bits is prescribed by a protocol. In this case, the first indication may be used to indicate the positions of bits. In other embodiments, the positions of bits may be prescribed by a protocol. For example, bits starting from an Nth bit are the one or more bits to be monitored. In this case, the first indication may be used to indicate the number of bits. In addition, in this embodiment, the first indication may be further used to indicate the positions of bits and the number of bits.

According to the claimed invention, the network device performs: sending indication information, wherein the indication information comprises a first indication, the first indication is used to indicate one or more positions of one or more bits to be monitored by a terminal, and the one or more bits to be monitored is at least one bit of DCI on a PDCCH; wherein the one or more positions of the one or more bits to be monitored is: one or more positions, in the DCI, of the one or more bits to be monitored.

It should be noted that in this embodiment of the present disclosure, information of one or more bits to be monitored may be indicated per terminal or per group of terminals. Specifically, that the first indication is used to indicate bit information of one or more bits to be monitored by a terminal includes:.

A specific grouping rule for the terminal group may be set based on an actual situation, and a definition of the terminal group is not further limited herein.

In this embodiment of the present disclosure, the network device sends the indication information, where the indication information indicates the bit information of the one or more bits to be monitored by the terminal, so that the terminal can learn the number of bits that need to be detected and the corresponding bit positions. Therefore, the terminal can use a detection algorithm with relatively low complexity to perform detection, thus avoiding complex detection processes of a conventional detection algorithm such as channel estimation, detection, and decoding. Therefore, this embodiment of the present disclosure can reduce complexity of PDCCH reception, thereby reducing power consumption in detection.

It should be noted that the detection algorithm used by the terminal may be set based on an actual requirement. For example, a sequence detection algorithm may be used for detection. The sequence detection algorithm only needs to perform a correlation operation on the terminal. In some optional embodiments, assuming that information bits transmitted on the PDCCH are two bits, and that other bits are all known bits, such as all-<NUM> bits, actually transmitted sequences are four bit sequences, and in a case in which an RNTI and a scrambling sequence are determined, four modulated symbol sequences may be determined.

In this case, the terminal may use a sequence detection method to detect the PDCCH, that is, perform sequence detection on a received symbol sequence, find a symbol sequence having a highest correlation with four modulation symbol sequences, and use the symbol sequence as the detected symbol sequence. In addition, the terminal determines <NUM>-bit information transmitted on the PDCCH.

Further, based on the foregoing embodiment, in this embodiment, the indication information further includes a second indication, and the second indication is used to indicate at least one of the following:.

In this embodiment, content in the second indication is used for PDCCH detection. Specifically, the content in the second indication may be set based on an actual requirement. For example, a part of the content may be prescribed, and a part of the content is indicated by the second indication.

Further, the indication information further includes a third indication, and the third indication is used to indicate at least one of the following:.

In this embodiment, the third indication is used for the terminal to perform PDCCH reception. Specifically, content in the third indication may be set based on an actual requirement. For example, a part of the content may be prescribed, and a part of the content is indicated by the third indication.

It should be noted that a first bit sequence on the PDCCH is configured by a network side or predefined, and the first bit sequence includes other bits than the one or more bits to be monitored among bits of the DCI.

For example, if the number of bits of the DCI on the PDCCH is <NUM>, and the one or more bits to be monitored are a first bit and a second bit, the first bit sequence includes a third bit to a twelfth bit. If each of the third bit to the twelfth bit is <NUM>, the first bit sequence is <NUM>.

In some optional embodiments, the terminal may assume that the other bits than the one or more bits to be monitored are a specific bit sequence (that is, the first bit sequence), and the terminal detects, based on the assumption, a symbol sequence transmitted on the PDCCH. In other optional embodiments, the network device may further indicate the bit sequence of the other bits (that is, the first bit sequence) than the one or more bits to be monitored; and the terminal may obtain corresponding bit information based on the bit sequence of the other bits, and therefore can detect, based on the bit information, the symbol sequence transmitted on the PDCCH.

In this embodiment of the present disclosure, because the bit information of the one or more bits to be monitored is indicated, the terminal obtains, by using the sequence detection method based on the bit information indicated by the network device, information transmitted in the one or more bits to be monitored. In other optional embodiments, sequence transmission may also be performed by using CCE resource sets whose aggregation levels are <NUM>, <NUM>, <NUM>, <NUM>, and <NUM> among PDCCH transmission resources. The transmitted sequence may be a pseudo-random sequence, a Gold sequence, an m sequence, a ZC sequence, a CGS sequence, a CAZAC sequence, or a sequence obtained through mutual modulation between at least two of the foregoing sequences, and the mutual modulation is element-wise multiplication of at least two bit sequences or element-wise multiplication of two symbol sequences. In this case, the terminal may perform sequence detection, and determine the transmitted information by detecting a sequence having a best correlation with a received signal.

It should be noted that, in this embodiment, the information transmitted on the PDCCH may be used to indicate at least one of the following:.

In this embodiment, the information transmitted on the PDCCH is the DCI correspondingly transmitted in the one or more bits to be monitored. Specifically, when the one or more bits to be monitored are at least two bits, each bit may be used to indicate one of the foregoing items, or different bit combinations may be used to indicate that the corresponding terminal is to perform an operation corresponding to the content indicated above. For example, when the one or more bits to be monitored include at least two bits, a bit combination of the one or more bits to be monitored indicates that the corresponding terminal is to perform a first operation, where the first operation is an operation corresponding to the information transmitted on the PDCCH, and bit combinations correspond to terminals on a one-to-one basis, or bit combinations correspond to terminal groups on a one-to-one basis.

For example, in the following description, it is assumed that the one or more bits to be monitored are two bits.

Specifically, in some optional embodiments, one bit may be used to indicate whether the terminal is to perform a first target operation, and the other bit may be used to indicate whether the terminal is to perform a second target operation, where the first target operation and the second target operation are different operations in the first operation.

In other optional embodiments, two bits may be used to indicate whether the terminal is to perform the first operation.

In still other optional embodiments, when the sequence of the one or more bits to be monitored is <NUM>, the one or more bits to be monitored may be used to indicate that a terminal numbered <NUM> is to perform the first operation; when the sequence of the one or more bits to be monitored is <NUM>, the one or more bits to be monitored may be used to indicate that a terminal numbered <NUM> is to perform the first operation; when the sequence of the one or more bits to be monitored is <NUM>, the one or more bits to be monitored may be used to indicate that a terminal numbered <NUM> is to perform the first operation; or when the sequence of the one or more bits to be monitored is <NUM>, the one or more bits to be monitored may be used to indicate that a terminal numbered <NUM> is to perform the first operation.

For better understanding the present disclosure, the following describes a PDCCH transmission process in detail by using two different implementations.

In one implementation, the network side indicates, by using RRC signaling, that the number of DCI bits to be monitored by the UE is <NUM>, and the indicated two bits to be monitored by the UE are an xth bit and a yth bit in a DCI bit sequence.

The xth bit is used to indicate whether the UE needs to monitor the PDCCH in the next DRX on-duration, and the yth bit is used to indicate whether the UE needs to perform CSI feedback.

Alternatively, in an NR unlicensed frequency band scenario, the two bits are used to indicate, to the UE, a remaining time of the channel obtained by the network side, such as <NUM>, <NUM>, <NUM>, or <NUM>.

In the other implementation, the network side indicates, by using RRC signaling, that the number of DCI bits to be monitored by the UE is <NUM>, and the indicated two bits to be monitored by the UE are an xth bit and a yth bit in a DCI bit sequence.

When the two bits are <NUM>, it indicates that UE#<NUM> needs to monitor the PDCCH within a next DRX on-duration after the current moment, or indicates that a UE group #<NUM> needs to monitor the PDCCH within a next DRX on-duration after the current moment.
