Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

For the existing mobile communication system, each information field in the DCI carries information of a specific function, but each information field in the DCI cannot be used for carrying other types of dynamic indication information, and thus cannot meet the requirements of the future mobile communication system.

One possible solution is to define explicit indication fields corresponding to new types of services/scenarios/requirements in DCI, introduce new bit fields (bit fields) but increase the complexity of DCI design, and increase the payload size (payload size) of DCI, which causes the increase of complexity of terminal side blind detection and the degradation of PDCCH transmission performance.

The invention provides a new method for dynamically indicating information, which effectively reduces the complexity of DCI design and reduces the complexity of terminal side blind detection by a method for additionally carrying different dynamic indicating information in different states of a designated information domain in DCI.

Example 1

The terminal may be a mobile phone (mobile phone), a tablet computer (pad), a computer with wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), etc.; but also UEs in various forms, mobile Stations (MSs), the terminal equipment (terminal device).

The search space is used as a search range for blind detection of the terminal, and different information is searched in different search spaces. The UE blind detection means that after the UE determines the starting position of the CCE, the UE intercepts and decodes the guessed DCI length at the starting position of the CCE, and if a Cyclic Redundancy Check (CRC) code in decoded information bits is the same as a CRC carried in the PDCCH, it is considered that the information bits carried by the current PDCCH are the currently transmitted PDCCH information.

Example 2

In this embodiment, the designated information field is a frequency domain resource allocation FDRA information field, and the dynamic indication information is indication information for notifying a physical downlink control channel PDCCH monitoring skip mode at the terminal side.

As an optional implementation manner, the multiple PDCCH monitoring skipping manners are specifically monitoring in a designated search space or all configured search spaces, and the network side device and the terminal determine that, in the DCI, the corresponding relationships between different states of a designated information field and different pieces of dynamic indication information carried in the DCI are as follows:

the FDRA information domain is the starting position of even numbered frequency domain resources, and the corresponding dynamic indication information X1 is used for monitoring a downlink control channel in a specified search space by the terminal;

the FDRA information domain is the starting position of odd-numbered frequency domain resources, and the corresponding dynamic indication information X2 is used for monitoring downlink control channels in all configured search spaces by the terminal;

and the terminal detects that the number of the initial position of the frequency domain resource which is indicated by the FDRA information domain in the received DCI is an even number, which indicates that the frequency domain resource carries dynamic indication information X1, and monitors a downlink control channel in a specified search space, wherein the specified search space can be a search space which is specified for the terminal by a network side.

And the terminal detects that the number of the initial position of the frequency domain resource which is indicated by the FDRA information domain in the received DCI is an odd number, which indicates that the frequency domain resource carries dynamic indication information X2, and monitors a downlink control channel in each search space configured by the base station.

In implementation, when the terminal determines that the DCI is not detected and received in the search space, the terminal monitors the downlink control channel according to the dynamic indication information carried in the DCI received last time.

The DCI in this embodiment may be DCI at a specified search space position, or may be DCI at any search space position.

The DCI is the DCI of the appointed search space position, the network equipment side indicates different dynamic indication information corresponding to different states to the terminal through different states of the appointed information field in the DCI of the appointed search space position, and the terminal receives the different dynamic indication information indicated by the DCI at the appointed search space position and executes the relevant operation.

Specifically, as shown in fig. 1, the base station configures 4 search spaces { SS #1ss # #2ss # #3ss #, 4} for the terminal, and further, the base station specifies a corresponding relationship between different initial frequency domain resource positions of the FDRA information domain and a PDCCH monitoring skip mode in DCI sent in SS # 1.

The terminal detects that the corresponding scheduling DCI is received in SS #1, and determines to monitor the downlink control channel in the designated search space according to the fact that the starting frequency domain resource position number of the FRDA information domain in the DCI is an even number, and the terminal detects that the corresponding scheduling DCI is received in SS #1, and determines to monitor the downlink control channel in all the configured search spaces according to the fact that the starting frequency domain resource position number of the FRDA information domain in the DCI is an odd number; or when the terminal determines that the DCI is not detected and received in the search space, the terminal monitors the downlink control channel according to the dynamic indication information carried in the DCI received last time.

The DCI can be the DCI of any search space position, after the terminal receives the DCI in each search space, the terminal receives the PDCCH monitoring skipping mode indicated by the network side according to the corresponding relation between the starting frequency domain resource position of the FRDA information domain in the DCI and different carried PDCCH monitoring skipping modes, and determines whether the subsequent monitoring skipping mode is to monitor only the search space receiving the DCI or to monitor all configured search spaces.

As an optional implementation manner, the multiple PDCCH monitoring skipping manners are specifically monitoring in a dynamic monitoring period, and the network side device and the terminal determine that, in the DCI, the corresponding relationship between different states of the designated information field and different pieces of dynamic indication information carried in the DCI may be:

if mod (I, 3) =1, the listening period is T1;

if mod (I, 3) =2, the listening period is T2;

if mod (I, 3) =3, the listening period is T3.

Where mod represents the correspondence, and I is the starting frequency domain resource location number of the FDRA information field.

The corresponding relationship between different states of the designated information field and different dynamic indication information carried by the designated information field may also be:

if mod (I, 3) =1, then the listening period is Tnew = ceil (T β 1);

if mod (I, 3) =2, the listening period is Tnew = ceil (T × β 2);

if mod (I, 3) =3, the listening period is Tnew = ceil (T β 3).

Wherein mod represents the corresponding relationship, I is the initial frequency domain resource location number of the FDRA information domain, and β 1, β 2, and β 3 are the listening period scaling factors dynamically indicated by the base station, for determining a new listening period. Of course, other numbers of scaling factors are also possible.

That is, a listening period T is configured in the search space, and the terminal determines a subsequent listening period according to the corresponding relationship and according to the FDRA state carried in the detected received DCI. Specifically, if the frequency domain resource starting number is I, if mod (I, 3) =1, the scaling factor corresponding to the listening period is β 1; if mod (I, 3) =2, the scaling factor corresponding to the listening period is β 2; if mod (I, 3) =3, the scaling factor for the listening period is β 3.

Example 3

In this embodiment, the designated information field allocates FDRA for the frequency domain resource, and the dynamic designation information X is M different power saving behaviors, and the number of the M different power saving behaviors is n.

Assuming that there are M =4 different power saving behaviors (power saving scheme) to indicate, several different power saving behaviors may be included:

n = #1, change DCI search space size of terminal;

n = #2, monitoring period and time domain offset in period of measurement signal of terminal;

n = #3, terminal channel state information, CSI, feedback;

n = #4, terminal data is scheduled across slots.

And the network side equipment indicates the power saving behavior adopted by the terminal through the initial position number of the frequency domain resource indicated by the FDRA information field in the DCI.

In this embodiment, the correspondence between different states of the designated information field and different pieces of dynamic indication information carried in the designated information field is as follows, where mod represents the correspondence, and I is the initial frequency domain resource location number of the FDRA information field:

when the terminal determines that the I satisfies the corresponding relationship according to the initial position number I of the frequency domain resource indicated by the FDRA information domain in the detected and received DCI, the terminal determines the adopted power saving behavior according to the corresponding relationship, as follows:

when I is determined to meet the corresponding relation 0, the DCI search space size of the terminal is changed according to the power saving behavior of n = # 1;

and when determining that the I meets the corresponding relation 1, according to the power saving behavior of n = #2, the monitoring period of the measurement signal of the terminal and the time domain offset in the period.

And when I is determined to meet the corresponding relation 2, feeding back the CSI of the terminal according to the power saving behavior of n = # 3.

And when determining that the I satisfies the corresponding relation 3, scheduling the terminal data in a cross-time slot mode according to the power saving action of n = # 4.

And the terminal executes corresponding related operations according to the power saving behavior corresponding to the initial position number of the frequency domain resource indicated by the FDRA information domain carried in the received DCI.

Example 4

In this embodiment, the specified information field allocates FDRA for the frequency domain resource, the dynamic indication information X is M different data channel repetition times, the corresponding relationship between different states of the specified information field and different dynamic indication information carried in the specified information field, and the corresponding relationship between the initial position number of the frequency domain resource indicated by the FDRA information field and the repetition times of data channel transmission.

The network side equipment indicates the repetition times of data channel transmission to the terminal through the initial position number of the frequency domain resource indicated by the FDRA information domain;

and the terminal determines the repetition times of data channel transmission according to the initial position number of the frequency domain resource indicated by the FDRA information field carried in the detected and received DCI, and transmits or receives the data channel in the channel according to the repetition times.

Specifically, the corresponding relationship between different states of the specified information domain and different carried dynamic indication information may be as follows:

if mod (I, M) =1, the channel repetition number is F1;

if mod (I, M) =2, the channel repetition number is F2;

if mod (I, M) =3, the channel repetition number is F3.

Wherein mod represents the corresponding relationship, and I is the initial frequency domain resource location number of the FDRA information domain.

The terminal determines that the terminal transmits or receives the data channel in the channel repeatedly for F1 times when the terminal determines that the I satisfies the corresponding relation 1 according to the initial position number I of the frequency domain resource indicated by the FDRA information field carried in the received DCI, the terminal transmits or receives the data channel in the channel repeatedly for F2 times when the terminal determines that the I satisfies the corresponding relation 2, and the terminal transmits or receives the data channel in the channel repeatedly for F3 times when the terminal determines that the I satisfies the corresponding relation 3.

Example 5

In this embodiment, the designated information field allocates FDRA for frequency domain resources, and the dynamic indication information X is M different channel priorities, where the channel priority may be a priority of a designated channel or a priority of any channel.

And the corresponding relation between different states of the specified information domain and different carried dynamic indication information is the corresponding relation between the parity of the initial position number of the frequency domain resource indicated by the FDRA information domain and the channel priority level.

Specifically, the example of the corresponding relationship between different states of the specified information domain and different carried dynamic indication information is as follows:

if mod (I, M) =1, then the channel priority is high priority;

if mod (I, M) =2, the channel priority is low priority.

Where mod denotes the correspondence, and I is the parity of the starting frequency domain resource location number of the FDRA information domain.

The terminal determines that the I is an even number and meets the corresponding relation 1 according to the initial position number I of the frequency domain resource indicated by the FDRA information field carried in the detected and received DCI, and then the terminal determines that the priority of the channel is high priority, which indicates that the channel cannot be punctured by other specific channels or cannot send other specific types of channels at the position overlapped with the channel resource; if it is determined that the correspondence 2 is satisfied when I is odd, the terminal determines that the priority of the channel is low priority, indicating that the channel can be punctured by another specific channel or another specific type of channel can be transmitted at a position overlapping with the channel resource.
