Method and Apparatus for Retransmission Scheduling and Control in Multi-Carrier Wireless Communication Networks

In one embodiment, a method of scheduling transmissions for a base station in a multi-carrier wireless communication network comprises scheduling initial transmissions of data packets for one or more users on a first carrier, without reserving scheduling capacity on the first carrier for retransmissions. Doing so increases the scheduled capacity of the first carrier for initial transmissions.

Apparatus, system and method for quasi-orthogonal multiple access

总体描述了提供准正交多址接入(QOMA)资源的eNodeB(eNB)、用户设备(UE)和方法。UE接收分配的正交多址接入(OMA)资源和非OMA(NOMA)资源。UE使用NOMA资源以高达最大NOMA速率和NOMA调制编码方案(MCS)的NOMA速率和NOMA MCS来传输数据，而无需从eNB接收明确的传输授权。eNB可以分配与不同最大速率、MCS、UE数目、UE类型、应用和大小相关联的多个NOMA区域。如果数据超过NOMA条件，或者UE不能使用所分配的NOMA资源传输数据，或者未从eNB接收到关于接收所传输数据的确认，则UE可以从eNB请求对OMA资源的明确授权，并且一旦接收到分配的OMA资源，则随后使用分配的OMA资源传输数据。
