Contention based resource configuration method and apparatus

摘要

A contention based resource configuration method is disclosed. The method includes: configuring, by a network device, a contention based resource parameter, wherein the contention based resource parameter comprises one or any combination of the following: a period and/or a frequency of a contention based resource block, the number of contention based resource blocks allocated once, a size of the contention based resource block, a modulation and coding scheme, and expected reception power; and notifying, by the network device, a user equipment of the contention based resource parameter. Through the technical solutions provided by the embodiments of the present invention, a network side may allocate a contention based resource more properly, and the user equipment may know the contention based resource parameter and use the contention based resource more properly and flexibly.

1. A contention based (CB) resource configuration method, the method comprising:
configuring, by a network device, a CB resource parameter, wherein the CB resource parameter comprises a number of CB resource blocks allocated in a single transmission time interval (TTI); notifying, by the network device, a user equipment (UE) of the CB resource parameter; allocating, by the network device, a CB resource according to the CB resource parameter; notifying, by the network device, the UE of a grant of the CB resource after notifying the UE of the CB resource parameter; detecting, by the network device, a probability of a conflict on the CB resource; and re-configuring, by the network device in response to the conflict on the CB resource being greater than or equal to a first conflict probability threshold, the CB resource parameter, wherein the re-configuring comprises increasing the number of the CB resource blocks allocated in the single TTI in the CB resource parameter.
