Problems solved by technology

[0004] Since the physical resources occupied by the PDCCH channel are limited, the number of control signaling transmitted on the PDCCH is limited, which limits the number of scheduling data packets and UEs, making the system capacity limited; in addition, due to the There are more and more services that need to transmit small packets. However, due to the small amount of data in small packets, it usually cannot fill up a MAC PDU. Therefore, it is necessary to carry padding bits in the MAC PDU, which reduces the efficiency of system resource usage and leads to system failure. waste of resources

Embodiment Construction

[0064] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0065] The control signaling transmitted on the PDCCH itself is carried on certain physical resources for transmission. Taking a cell with a bandwidth of 5MHz as an example, there are usually only a dozen control signalings that can be carried in one Transmission Time Interval (TTI), which include both uplink and downlink scheduling informatio...

Abstract

The present invention provides a group-based scheduling method, UE and base station. The method includes that the UE obtains a group scheduling identifier, and the group scheduling identifier is used to indicate the group scheduled by the control signaling on the PDCCH; the UE receives the masked control signaling on the PDCCH, and decodes the packet according to the group scheduling identifier. Covering the control signaling; the UE receives a MAC PDU according to the control signaling, and the MAC PDU includes data packets of at least one UE in the same group; the UE receives the MAC PDU according to the at least one of the MAC PDU The corresponding relationship between the position of the UE data packet and the position of the PUCCH feedback resource, acquiring the position of the PUCCH feedback resource corresponding to the position of the UE data packet, and sending ACK feedback information on the position of the corresponding PUCCH feedback resource. The embodiments of the present invention can improve resource utilization and system capacity.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a group-based scheduling method, UE and network equipment. Background technique [0002] In a Long Term Evolution (LTE) system, a base station (eNodeB, eNB) uses a physical downlink control channel (Physical Downlink Control Channel, PDCCH) to transmit control signaling for scheduling user equipment (User Equipment, UE), when When scheduling the data of the UE in the connected state, the control signaling is masked with the Cell Radio Network Temporary Identity (C-RNTI) of the UE. The control signaling is the scheduling information of the UE, including The physical channel resources and the specific modulation and coding scheme (Modulation and Coding Scheme, MCS) information, etc., after receiving the control signaling transmitted on the PDCCH, the UE uses the C-RNTI de-masking control signaling of the UE to obtain the de-masking related information carried in the subse...
