    Abstract: Paging congestion control in a wireless communications system is described. Various described methods and apparatus are well suited for use in a peer to peer wireless communications system, e.g., an ad hoc peer to peer wireless network in which decisions are made in a decentralized manner. Wireless terminals, e.g., mobile nodes, monitor other paging activities going on and make back-off, e.g., yielding, decisions with regard to paging based on the results of the monitoring. During a first time interval paging indicator signals are transmitted on paging indicator resources by devices intending to transmit paging signals. During a second time interval paging signals are transmitted on paging signaling resources. Monitored and processed detected paging indicator signals are used by a wireless terminal in deciding whether or not to transmit a paging indicator signal and/or a paging signal.

    Abstract: The present invention provides a method for obtaining bearer condition during a handover of UE. The method includes: receiving, by a mobile management entity (MME), information of at least one bearer allowed to be accepted by a target base station (eNB) when the eNB makes an admission control for a UE based on received bearer information of the UE during handover of the UE; updating, by the MME, a UE-AMBR used by the target eNB based on the received at least one bearer. The present invention also provides an MME which enables the target side obtain actual bearer condition during handover of a UE.

    Abstract: A technique for operating a wireless communications system that supports multi-user multiple-input multiple-output (MU-MIMO) communications between a base station and multiple mobile stations involves generating inter-cell interference information at the mobile stations and providing the inter-cell interference information to the base station. The base station uses the inter-cell interference information to calculate channel quality indicators (CQIs) and then makes scheduling decisions in response to the CQIs. Data is transmitted from the base station to the mobile stations according to the scheduling decisions.
