The present invention claims the priority of the Chinese patent application submitted to the Chinese Patent Office on May 18, 2021, with the application number 202110541070.8, and the title of the invention is "Control Channel Monitoring Method and Device", the entire content of which is incorporated by reference in the present invention middle.

technical field

The present application belongs to the technical field of communication, and in particular relates to a control channel monitoring method and equipment.

Background technique

The fifth generation (5th ^Generation , 5G) communication system supports the configuration of one or more cells (or carriers) for the terminal. If the channel quality of some cells is not good enough or the probability of channel blocking is high, the network side device can configure the terminal for the terminal. Cross-carrier scheduling is to configure control channels in other cells with better channel quality (for example, primary cell, PCell) to schedule data of other cells (for example, secondary cell, SCell) across carriers.

The scheduling cell may be in a self-scheduling mode, in which case the cell only schedules itself. If the scheduling cell is configured with cross-carrier scheduling, it can also schedule one or more scheduled cells other than itself. The scheduled cell does not have its own control channel and can only be scheduled by one dispatching cell.

In related technologies, a cell can only be scheduled by one scheduling cell (that is, it can only be self-scheduled or scheduled by another cell), and the primary cell can only be scheduled by the primary cell itself.

The control channel monitoring method and device provided in the embodiments of the present application will be described in detail below through some embodiments and application scenarios with reference to the accompanying drawings.

As shown in FIG. 2 , the embodiment of the present application provides a method 200 for monitoring a control channel. The method can be executed by a terminal. In other words, the method can be executed by software or hardware installed in the terminal. The method includes the following steps.

S202: The terminal determines the monitoring capability of a control channel; the control channel is used to schedule a first cell, and the first cell can be scheduled by at least two scheduling cells.

The control channel mentioned in various embodiments of the present application may be a physical downlink control channel (Physical Downlink Control Channel, PDCCH), and the subsequent embodiments mostly use the PDCCH as an example to illustrate the control channel.

The monitoring capability of the control channel is usually used to indicate the capability of the terminal to monitor the control channel, for example, including: the blind detection of control channel resources of multiple scheduling cells scheduling the first cell on the time domain unit based on the reference SCS The total restriction, the blind detection control channel resource restriction of at least one scheduling cell scheduling the first cell in the time domain unit based on the reference SCS, and the like.

In this step, the terminal can determine the monitoring capability of the control channel according to predefined rules (such as agreement agreement); it can also determine the monitoring capability of the control channel according to the parameters configured by the network side equipment.

For example, the terminal supports multiple monitoring capabilities, and the terminal selects a monitoring capability according to predefined rules; for another example, the terminal reports the various monitoring capabilities it supports to the network-side device, and the network-side device can configure scheduling parameters for the terminal, etc., and the terminal according to The scheduling parameters and the like can obtain the monitoring capability used by the currently monitored PDCCH.

The above control channel is used to schedule the first cell. The first cell may be a cell that transmits a data channel for the terminal. The first cell can be scheduled by at least two scheduling cells, that is, the above control channel may belong to at least two scheduling cells.

In subsequent embodiments, all the cells capable of calling the first cell may be referred to as the first scheduling cell group. In an example, the first cell is the primary cell (Pcell), and the first scheduling cell group includes the Pcell and a secondary cell (Scell). In subsequent examples, an S-Scell may be used to represent the Scell capable of scheduling the Pcell.

S204: Determine at least one of the following related to the control channel according to the monitoring capability: processing time; scheduling restriction; scheduling time indication definition.

In this embodiment, the network-side device can configure the corresponding relationship between monitoring capabilities and processing time, scheduling restrictions, scheduling time indication definitions, etc.; or, the agreement stipulates the corresponding relationship between monitoring capabilities and processing time, scheduling restrictions, scheduling time indication definitions, etc. . In this way, the terminal can determine at least one of the following related to the control channel according to the determined monitoring capability: processing time; scheduling restriction; scheduling time indication definition.

3) The preparation time of the uplink data channel scheduled by the control channel. For example, the preparation time of a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) scheduled by the PDCCH.

4) The calculation or reporting time of the channel state information (Channel State Information, CSI) of the control channel scheduling. For example, the transmission of the Aperiodicity-Channel State Information-Reference Signal (A-CSI-RS) scheduled by the PDCCH, and the calculation or reporting time of the CSI corresponding to the A-CSI-RS.

5) The preparation or reception time of the A-CSI-RS scheduled by the control channel. For example, the preparation or reception time of the A-CSI-RS scheduled by the PDCCH.

In this embodiment, considering that the first cell can be scheduled by at least two scheduling cells, that is, the terminal may need to monitor the control channels of at least two scheduling cells, therefore, the monitoring capability of the control channel may be redefined. Time can be relaxed appropriately to reduce the complexity of terminal implementation. For example, each of the above processing times may be respectively greater than the target time, and the target time may be the corresponding time when the terminal monitors the control channel of a scheduling cell in the related art, so as to help reduce the complexity of terminal implementation.

In this embodiment, considering that the first cell can be scheduled by at least two scheduling cells, the subcarrier spacing (SubCarrier Spacing, SCS) of at least two scheduling cells may be different, therefore, the granularity of the above processing time may be determined according to the reference SCS For example, the above-mentioned processing time is how many symbols and how many time slots are under the reference SCS, and the reference SCS will be introduced in subsequent embodiments.

In this example, for example, the start time of K0/k2 is not defined by the last symbol of the PDCCH, but by the end position of the time slot of the scheduling cell with the smallest SCS among the two scheduling cells. The time slot may be the time slot corresponding to the transmission time of the above PDCCH on the scheduling cell with the smallest SCS. For the definition of K0/k2, refer to the introduction in the above 1).
