Problems solved by technology

[0004] In mobile communication (e.g., 5G) systems, the use of high subcarrier spacing (e.g., 480kHz or above) can lead to various challenges
For example, constraints on Physical Downlink Control Channel (PDCCH) monitoring per slot and constraints on the number of non-overlapping Control Channel Elements (CCEs) per slot may be difficult to meet, and if each downlink control information (DCI) only schedules one Physical Downlink Shared Channel (PDSCH), then achieving high throughput can also be challenging

Embodiment 1

[0054] Embodiment 1: The UE capability of aggregating the maximum BD / CCE on multiple time slots is a UE capability (for example: an optional capability or a specified capability for certain frequency bands, such as above 52.6 GHz). Additional capability values ​​may be signaled (i.e., signaled by UE to gNB) as follows:

[0055] Alternative 1: For a value μ and a maximum non-overlapping CCE Y, the UE may report the capability N μ , such that:

[0056] (i) UE only needs any given N μ Processing maximum N in consecutive time slots μ Under the condition of ×Y non-overlapping CCEs, the UE can process the maximum N μ ×Y non-overlapping CCEs.

[0057] (ii) When M≤N μ When , the network can configure the maximum non-overlapping aggregated CCEs based on M timeslots.

[0058] Alternative 2: For a value μ per slot and a maximum non-overlapping CCEY, the UE may report a capability X, where Y≤X. Then, at any N μ The total number of non-overlapping CCEs configured in a period of slo...

Embodiment 2

[0060] Embodiment 2: In this embodiment, for higher SCS (such as 480kHz, 960kHz, or 1920kHz), the definition of the maximum BD / CCE is based on multiple time slots. Alternatively, when the maximum BD / CCE is defined based on multiple slots (e.g., N slots), the BD / CCE can be limited to N 0 in consecutive time slots.

Embodiment 2a

[0061] Embodiment 2a: In this embodiment, the definition of the maximum BD / CCE based on multiple time slots in Embodiment 2 is limited to N in N time slots 0 within consecutive time slots (i.e. N-N 0 BD / CCE may not exist in slots), where:

[0062] Alternative 1: N 0 The value of is determined by UE capabilities, or

[0063] Option 2: N 0 The value of is a predetermined (eg, specified by the standard) quantity.

[0064] N 0 The position of consecutive slots within the duration of N slots may be arbitrary, or additional constraints may apply to the position. For example, these N timeslots within repeated sets of N time slots may be required 0 The positions of consecutive time slots form a fixed pattern.

Abstract

The present invention relates to a system and method for monitoring and scheduling. In some embodiments, the method includes receiving, by a user equipment (UE), the downlink control information (DCI) specifying a schedule of a first physical downlink shared channel (PDSCH) and a second PDSCH.
