Resource scheduling indication method and device

Abstract

The invention relates to the communication field, and discloses a resource scheduling instruction method and device, which are used to reduce system signaling overhead. The method is as follows: A new multi-frame resource scheduling method is designed for new service requirements, that is, the configured transmission pattern is notified to the UE in advance, and then scheduling signaling is sent to the UE, so that the UE combines the obtained transmission pattern to realize scheduling multiple frames at a time. In this way, the system overhead caused by sending scheduling signaling can be effectively saved, the system operating load can be reduced, and system performance can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource scheduling instruction and processing method and device. Background technique [0002] For LTE and LTE-A systems, as defined in 3GPP TS36.211 / 212 / 213 and other related standards, PDCCH (Physical Downlink Control Channel) is used to carry scheduling signaling for uplink / downlink traffic channels, namely Uplink grant / Downlink grant, and Relevant signaling information formats are defined for different transmission modes. At the same time, the relevant timing relationship is also defined, specifically: see figure 1 and figure 2 As shown, when scheduling downlink resources, each PDCCH schedules the PDSCH (physical downlink service channel) of the subframe; when scheduling uplink resources, it is necessary to reserve the processing delay for the UE (user equipment) to detect control signaling and prepare for uplink channel transmission. For example, for the FDD system, ...

Problems solved by technology

[0008]Under the existing technology, dynamic resource scheduling is suitable for flexible data transmission, but the disadvantage is that the overhead of scheduling signaling is relatively large, so it is more suitable for uplink / downlink data transmission For services with a large amount of traffic, because the overhead of scheduling signaling is more in line with expectations; and semi-persistent scheduling is more suitable for stable services, such as voice services (VoIP), because such services have better periodicity and stability sex

[0009] However, with the enhancement of wireless mobile communication systems, the types of services supported are becoming more and more abundant, such as M2M (machine to machine, machine to machine), new services The amount of transmitted data may be small, but the periodicity is not as long as the stable duration of the VoIP service. At this time, if the dynamic resource scheduling method is used, the overhead of scheduling signaling will be too large, which will bring operating load to the system. Using the SPS scheduling method requires frequent resource triggering and release, which will also lead to excessive scheduling signaling overhead, and will also bring operating load to the system.
