Method, Apparatus, and System for Processing Radio Link Failure

Номер: US20120002538A1
Автор: DONG Chen, Jie Ma, Shukun Wang
Принадлежит: Huawei Technologies Co Ltd

A method for processing radio link failure (RLF) includes, when a user equipment (UE) communicates with a network through two or more carriers, if downlink RLF occurs on at least one of the two or more carriers, determining whether there is a carrier on which no downlink RLF occurs, among the two or more carriers, and sending a message to the network through a dedicated control channel (DCCH) of the carrier on which no downlink RLF occurs if there is the carrier on which no downlink RLF occurs, wherein the message carries information of at least one of a carrier and a cell on which RLF occurs and instructs the network to perform RLF processing for the carrier on which the downlink RLF occurs, or stopping sending information on an uplink dedicated physical control channel (DPCCH) of the carrier on which the downlink RLF occurs.

A device receives available capacity and used capacity associated with a network, receives a connection request from a user device in the network, and receives a maximum capacity threshold associated with the network. The device calculates a minimum capacity threshold and a medium capacity threshold, associated with the network, based on the maximum capacity threshold. The device also determines whether to admit or deny the connection request based on the available capacity, the used capacity, the minimum capacity threshold, the medium capacity threshold, and the maximum capacity threshold. The device further allocates, when the connection request is to be admitted and based on resource availability associated with the network, a particular bit rate, for a particular quality of service (QoS) class, to the connection request.

Limited duty cycle fdd system

Номер: US20120002578A1
Автор: Peter Gaal, Tingfang JI
Принадлежит: Qualcomm Inc

Acknowledgment bundling has been defined for Long Term Evolution (LTE) Time Division Duplex (TDD) systems due to asymmetric DL/UL partitioning. In the case of Frequency Division Duplex (FDD) with a limited uplink (UL) duty cycle, there may be asymmetry associated with a downlink transmission and an associated uplink acknowledgment. For example, there may be a physical downlink shared channel (PDSCH) and a physical uplink control channel (PUCCH) hybrid automatic repeat request acknowledgment (HARQ-ACK) asymmetry. Interference between downlink and uplink transmissions may be a factor contributing to the limited UL duty cycle in an FDD system. For an FDD system having a limited mobile transmission duty cycle, both DL and UL performance may be significantly degraded without proper mitigation techniques. According to certain embodiments of the present disclosure, various HARQ and scheduling techniques may be utilized for minimizing loss due to the limited UL duty cycle.

A method for allocating resources for a scheduling request indicator (SRI) is disclosed. An SRI cycle period for use by user equipment (UE) within a cell is transmitted from a NodeB in a cell to UE within the cell. The NodeB transmits a specific SRI subframe offset and an index value to the particular UE within the cell. The specific SRI subframe offset and the index value enable the UE to determine a unique combination of cyclic shift, RS orthogonal cover, data orthogonal cover, and resource block number for the UE to use as a unique physical resource for an SRI in the physical uplink control channel (PUCCH).

Disclosed are channel management methods in a multicarrier structure in a mobile communication system. Uplink (UL) and downlink (DL) channel management methods in a carrier aggregation environment are used as the channel management methods. In DL, a base station determines a component carrier (CC) of an unstable radio channel state, stops data retransmission by the CC, and notifies a terminal of retransmission stop. In UL, the base station determines a CC of an unstable radio channel state and instructs the terminal to stop data retransmission by the CC, and the terminal stops the data retransmission and initializes a retransmission buffer. Using the channel management methods in the mobile communication system employing the multicarrier structure, an increase in the number of unnecessary retransmissions is prevented, so that unnecessary retransmission and power consumption of the terminal can be reduced and the waste of radio resources and the degradation of base station performance due to unnecessary retransmission can be prevented.
