摘要： An apparatus for allocating radio resources shared among a plurality of network operators is provided. Each network operator has at least one scheduling entity, SE, and a respective resource allocation, RA, probability for being selected for radio resource allocation during a transmission time interval, TTI. The apparatus includes a processor and a memory. The memory contains instructions executable by the processor that are configured to cause the apparatus, within a TTI, to select a network operator of the plurality of network operators for resource allocation within the TTI based at least in part on the RA probability of the network operator, allocate radio resources to an SE of the selected network operator within the TTI and update the RA probability of selecting each of the plurality of network operators for a next selection of resource allocation.

摘要： A mobile phone network node may determine traffic load associated with a mobile phone network and initiate discontinuous transmission at a frame level, based at least in part upon, determining that the traffic load is less than a first threshold. The mobile phone network node may further initiate discontinuous transmission at a subframe level, based at least in part upon, determining that the traffic load is greater than the first threshold and less than a second threshold and initiate discontinuous transmission at a symbol level, based at least in part upon, determining that the traffic load is greater than the second threshold.

摘要： According to certain embodiments, methods and systems for providing broadcast multicast service include transmitting, by a network node, a first transmission of multicast content data to wireless devices at a first quality of service level and a second transmission of multicast content data to the wireless devices at a second quality of service level. The second quality of service level may be of a higher quality of service than the first quality of service. Feedback may be received from at least one wireless device in the broadcast service area. In response to the feedback from the wireless devices, one or more transmission parameters associated with a subsequent transmission of the multicast content data may be adjusted.

摘要： A base station (10) dynamically allocates users among broadcast carriers and dynamically allocates carrier resources between broadcast and unicast service, based on the number of users actually receiving broadcast service on a carrier. The base station (10) periodically measures (204) the number of broadcast-only users registered to a carrier. As the number of such users decreases, the remaining idle broadcast-only are transferred (212) to other carriers transmitting the same broadcast content, and carrier resources are reallocated (208) to unicast service. When the carrier is moderately loaded, it may accept broadcast users transferred from other, lightly-loaded carriers, which are attempting to shed users to reallocate resources to unicast service. As the carrier becomes more heavily loaded, it will refuse (216) to accept transferred broadcast users. When the carrier's load reaches an upper threshold, the base station (10) allocates (220) resources of a new carrier to broadcast service, and moves users to the new carrier.
