Abstract

The embodiment of the invention provides a contention based (CB) resource configuration method. The method comprises the following steps: the network equipment configures one or multiple first objects capable of using the CB resource, wherein the one or multiple first objects belong to a proper subset of all first objects; and the network equipment sends the first CB resource information which is used for indicating that the one or multiple first objects can use the CB resource, wherein the first object comprises one or any combination of a wireless bearer, user equipment and a user equipment group. The embodiment of the invention also provides a CB resource using method and network equipment as well as user equipment, and is applicable to relay scenes or discontinuous reception scenes. Through the scheme, the probability of conflict during the uplink transmission by using the CB resource can be reduced, the energy of the user equipment can be saved, and the implementation complexity of the user equipment can be lowered.

Description

technical field [0001] The invention relates to the communication field, in particular to a configuration technology based on contention resources. Background technique [0002] In the communication system, in order to reduce the delay of the signaling plane and the user plane, several schemes are proposed. These technical solutions include reducing the scheduling period of RACH (Random Access Channel, Random Access Channel), reducing the period of PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel), reducing UE (User Equipment, user equipment) and eNB (Evolved Node B, the processing delay of the evolved base station) and the use of CB (Contention Based, contention-based) resources for uplink transmission. [0003] Using CB resources for uplink transmission can quickly and effectively transmit a small amount of data when there is no dedicated uplink transmission resource. The CB resource is not specific to each UE, but can be used by all UEs in the cel...
