Embodiment 1

[0070] by image 3 For example, the network side configures a total of 3 cells for the UE: Cell1, Cell2 and Cell3, and the subcarrier intervals are all 15 kHz, that is, μ=0. The span of Cell 1 is merged into (2,2), and the spans of Cell 2 and Cell 3 are merged into (4,3).

[0071] For Cell 1, 7 spans are configured in one slot. Specifically, these 7 spans determine the span pattern (pattern) in the slot according to the configured PDCCH monitoring occasion. In Cell 2 and Cell 3, a slot Configure 3 spans respectively, and the span pattern is as follows image 3 shown.

[0072] suppose

[0073] For span1 of Cell 1, the combined cell-span set of overlapping spans in the time domain is {Cell 1(2,2), Cell2(4,3)}, that is, the number of overlapping cells is 2, namely The number of non-overlapping CCEs and blind detections that need to be monitored by the span UE are:

[0076] For span1 of Cell 2, such as Figure 4 As shown, the merged set of cell-spa...

Embodiment 2

[0080] by Figure 5 For example, the network side configures four cells in total for the UE: Cell1, Cell2, Cell3 and Cell4, and the subcarrier spacing is 15 kHz. The spans of Cell 1 and Cell4 are merged into (2,2), and the spans of Cell 2 and Cell3 are merged into (4,3).

[0081] For Cell 1, 7 spans are configured in one slot. Specifically, these 7 spans are determined according to the configured PDCCHmonitoring occasion to determine the span pattern (pattern) in the slot, and 3 are configured in each slot of Cell 2 and Cell 3. span, span pattern such as Figure 5 shown.

[0082] For span1 of Cell 1, such as Figure 5 As shown, the merged set of cell-spans of overlapping spans in the time domain is {Cell 1(2,2), Cell 2(4,3), Cell 4(2,2)}, that is, the number of overlapping cells is 3, namely The number of non-overlapping CCEs and blind detections that need to be monitored by the span UE are:

Embodiment 3

[0089] For each scheduling cell and each span of each time slot, when the subcarrier spacing is μ and the spans are combined into (X, Y), the number of non-overlapping CCEs monitored by the span is not greater than and the minimum value in;

[0090] For each scheduling cell and each span of each time slot, when the UE subcarrier spacing is μ and the spans are combined into (X, Y), the number of PDCCHs monitored by the span is not greater than and The minimum value in .

[0091] In the above embodiment, if Figure 3-Figure 5 As shown, the symbol boundaries of different cells are aligned, that is, the symbol boundaries of multiple non-target cells can be the same as the symbol boundaries of the target cell; Radio Head, RRH) mode), the distance from different cells to the UE may be different, so the time when the signal arrives at the UE may be different (that is, the timing of receiving the signal from each cell may be different), causing span misalignment, that is, mult...

Abstract

The embodiment of the invention discloses a method and device for determining the monitoring quantity and communication equipment, and belongs to the technical field of communication. The method for determining the monitoring quantity comprises the steps: determining a cell-span merging set corresponding to a target span, wherein the cell-span merging set comprises span merging of a plurality of non-target cells and span merging of a target cell, and the span of the plurality of non-target cells is overlapped with the target span in a time domain; determining the number of first downlink carriers and the number of second downlink carriers according to the cell-span merging set; and determining the number of non-overlapping CCEs and / or the number of PDCCH candidates monitored by the UE in the target span according to the number of the first downlink carriers and the number of the second downlink carriers. According to the technical scheme of the invention, the number of UE monitoring resources can be determined in low-delay and high-reliability services.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for determining a monitoring quantity, and communication equipment. [0002] NSSF Background technique [0003] Compared with previous mobile communication systems, future 5G mobile communication systems need to adapt to more diverse scenarios and business requirements. The main scenarios of 5G include Enhanced Mobile Broadband (eMBB), Ultra-reliable and Low Latency Communications (URLLC), Massive Machine Type of Communication (mMTC), These scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage. [0004] In related technologies, the maximum number of physical downlink control channel (Physical Downlink Control Channel, PDCCH) candidates and the number of non-overlapped (non-overlapped) control channel elements (Control Channel Element, CCE) monitored by a user equipment (User Equipme...
