Patent Description:
In a New Radio (NR) system, a slot or a symbol is taken as a scheduling unit. Each slot includes <NUM> Orthogonal Frequency Division Multiplexing (OFDM) symbols. The frame structure of an NR system changes flexibly. There may be one or more Downlink (DL) symbols, one or more UpLink (UL) symbols and one or more flexible symbols in one slot. The flexible symbol may also be called an unknown symbol, and the flexible symbol may be rewritten, through signaling, to be used for DL transmission or UL transmission.

A specific slot format may be configured through Slot Format Indication (SFI) information. A base station sends an SFI in a Group Common Physical Downlink Control Channel (GC-PDCCH). A network configures a search space for the GC-PDCCH, and the GC-PDCCH is transmitted in the search space configured by the network.

Generally, a network may configure corresponding time-domain information for a search space, for example, a monitoring period of the search space. The network may also configure corresponding time-domain information for dynamic SFI information, for example, a monitoring period of the dynamic SFI information. A present time-domain information configuration manner has the following problems.

<CIT>, "Remaining details on group-common PDCCH" and "On signalling mechanisms to support dynamic TDD UL-DL reconfiguration" provide respective technical solutions; however, the above mentioned problem still remains unsolved.

Embodiments of the present disclosure provide a resource configuration method and device, and a computer storage medium, which may solve at least one of the above technical problems.

By adopting the technical solutions of the embodiments of the present disclosure, under the condition that the network device configures a monitoring period or simultaneously configures two monitoring periods, the terminal may determine the specific time period based on which the dynamic SFI information is received. In addition, the network device not only configures the monitoring period but also monitors the time-domain starting location of the dynamic SFI information in the monitoring period, so that the terminal is not required to detect the dynamic SFI information at all possible time-domain locations, detection complexity of a receiver is reduced and, meanwhile, power consumption of the terminal is reduced.

The drawings described here are adopted to provide a deeper understanding to the present disclosure and form a part of the application. Schematic embodiments of the present disclosure and descriptions thereof are adopted to explain the present disclosure and not intended to form improper limits to the present disclosure. In the drawings:.

For making the technical solutions of the embodiments of the present disclosure convenient to understand, related configurations involved in the embodiments of the present disclosure will be described below.

The following slot format configuration manners are mainly adopted for a system.

In an implementation mode, a network configures a UL/DL slot structure by semi-persistent slot format configuration. Semi-persistent slot format configuration may indicate the numbers and locations of DL symbols, UL symbols and flexible symbols in one slot and the like. In another implementation mode, the network may send an SFI through dynamic signaling (for example, a GC-PDCCH) to dynamically indicate the slot structure. Herein, the SFI may indicate the DL symbols, the UL symbols and the flexible symbols. In addition, the SFI may dynamically indicate the slot structure in combination with semi-persistent slot format configuration. The DL symbols and UL symbols in the slot structure configured by semi-persistent slot format configuration may not be changed through the dynamic SFI, but the flexible symbols may be changed into DL symbols or UL symbols through the dynamic SFI or are not changed through the SFI.

<FIG> is a first flowchart of a resource configuration method according to an embodiment of the present disclosure. As shown in <FIG>, the resource configuration method includes the following operations shown in blocks <NUM> and <NUM>.

In block <NUM>, a terminal receives first configuration information and/or second configuration information sent by a network device, the first configuration information being configured to indicate a first time period corresponding to a first search space and the second configuration information being configured to indicate a second time period corresponding to first UL/DL configuration information.

In the embodiment of the present disclosure, the terminal may be any device capable of communicating with a network, for example, a mobile phone, a tablet computer, a notebook computer, a game console, a palm computer and a desktop computer.

In the embodiment of the present disclosure, the network device is a base station, for example, a gNB in a 5th-Generation (<NUM>) system and an Evolved Node B (eNB) in a 4th-Generation (<NUM>) system.

In the embodiment of the present disclosure, the first configuration information is configured to indicate the first time period corresponding to the first search space. In an implementation, the first search space is a search space for a GC-PDCCH, and the first time period refers to a monitoring period of the search space for the GC-PDCCH. For example, the first time period is <NUM> slots.

In the embodiment of the present disclosure, the second configuration information is configured to indicate the second time period corresponding to the first UL/DL configuration information. In an implementation mode, the first UL/DL configuration information is dynamic SFI information. Herein, the dynamic SFI information is borne in the GC-PDCCH. The second time period refers to a monitoring period of the dynamic SFI information. For example, the second time period is <NUM> slots.

In the embodiment of the present disclosure, the first time period may be different from the second time period. There are no limits made thereby. The first time period may be the same as the second time period.

In the embodiment of the present disclosure, the network device may configure one piece of configuration information, i.e., the first configuration information or the second configuration information, for the terminal. The network device may also simultaneously configure two pieces of configuration information, i.e., the first configuration information and the second configuration information, for the terminal.

In block <NUM>, the terminal selects one piece of configuration information from the first configuration information and/or the second configuration information as target configuration information, and receives the first UL/DL configuration information based on a time period corresponding to the target configuration information.

In the embodiment of the present disclosure, the following conditions exist for the operation that the terminal determines the target configuration information (i.e., a target period) configured to receive the first UL/DL configuration information.

A first condition: in a case where the terminal receives the first configuration information sent by the network device, the terminal determines the first configuration information as the target configuration information.

For example, in a case where the network device does not configure a monitoring period T1 of the dynamic SFI information and the network device configures a monitoring period T2 of the search space where the dynamic SFI information is located, the terminal monitors the dynamic SFI information according to the period T2.

A second condition: in a case where the terminal receives the second configuration information sent by the network device, the terminal determines the second configuration information as the target configuration information.

For example, in a case where the network device configures the monitoring period T1 of the dynamic SFI information and does not configure the monitoring period T2 of the search space where the dynamic SFI information is located, the terminal monitors the dynamic SFI information according to the period T1.

A third condition: in a case where the terminal receives the first configuration information and second configuration information sent by the network device, the terminal determines the second configuration information as the target configuration information.

For example, in a case where the network device configures the monitoring period T1 of the dynamic SFI information and also configures the monitoring period T2 of the search space where the dynamic SFI information is located, the terminal monitors the dynamic SFI information according to the period T1. Herein, T1 may be equal to unequal to T2. In a case where T1=<NUM> slots and T2=<NUM> slots, the terminal monitors the dynamic SFI information according to T1 =<NUM> slots.

<FIG> is a second flowchart of a resource configuration method according to an embodiment of the present disclosure. As shown in <FIG>, the resource configuration method includes the following operations shown in blocks <NUM>, <NUM> and <NUM>.

In block <NUM>, a terminal receives first configuration information sent by a network device, the first configuration information being configured to indicate a monitoring period of a search space where first UL/DL configuration information is located.

In block <NUM>, the terminal receives third configuration information sent by the network device, the third configuration information being configured for determining a time-domain starting location of the first UL/DL configuration information in the monitoring period.

In the embodiment of the present disclosure, that the third configuration information is configured for determining the time-domain starting location of the first UL/DL configuration information in the target time period includes that:.

For manner <NUM>), the third configuration information directly configures the starting slot location of the dynamic SFI information in a time period. For example, a fourth slot in a time period is the starting slot location.

For manner <NUM>), the third configuration information configures a slot offset of the dynamic SFI information relative to the reference slot in a time period, so that resources may be saved. Furthermore, the reference slot is determined based onone of the following manners:.

For example, a network configures a slot offset (SFI-offset-slot) of the dynamic SFI information in a monitoring period for the terminal. In an implementation mode, the slot offset is a slot offset relative to a first slot of the monitoring period (slot is taken as a unit).

For example, the network configures that the monitoring period is <NUM> slots, and a value range of the slot offset is {<NUM>, <NUM>, <NUM>, <NUM>, <NUM>}. Herein, the slot offset is relative to the first slot of the monitoring period. In an implementation mode, the first slot of the monitoring period may be determined through a slot index (Ind_slot) corresponding to a formula mod(lnd_slot, <NUM>)=<NUM>, where mod(A, B) represents a remainder obtained by dividing B by A. According to the formula, it can be seen that slot <NUM>, slot <NUM>, slot <NUM>, slot <NUM>. represent the first slot of the monitoring period, and the slot offset is the number of offset slots relative to the first slot of the monitoring period in each monitoring period.

In the embodiment of the present disclosure, the terminal receives the third configuration information sent by the network device through RRC signaling or common control signaling or dedicated control signaling.
