Resource scheduling indication method and device

Abstract

The invention relates to the field of communication, and discloses a resource scheduling indication method and a device, aiming to reduce the signaling cost of a system. The method comprises the following steps: setting a novel multi-frame resource scheduling mode according to novel business demands, i.e. informing UE (Unified Equipment) of a configured transmission pattern in advance, and sending scheduling signaling to the UE, and combining the UE and the obtained transmission pattern to simultaneously schedule data transmission of a plurality of sub-frames. Therefore, the cost of the system to send the scheduling signaling can be reduced effectively, the operating load of the system can be decreased, and the performance of the system 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. Therefore, it is more suitable for services with large amounts of uplink / downlink data transmission, because the overhead of scheduling signaling is only It is more in line with expectations; while semi-persistent scheduling is more suitable for stable services, such as voice services (VoIP), because such services have better periodicity and stability

[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 may transmit a small amount of data, but the periodicity is not as stable as VoIP services The duration is long. 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. However, using the SPS scheduling method requires frequent resource triggering and release, which is also It will lead to excessive overhead of scheduling signaling, which will also bring operating load to the system
