    摘要: A wireless base unit (102) supporting carrier aggregation determines a truncation time period (159, 169) in order to create a reduced subframe component (154, 164) on an additional component carrier (120) such that the truncated subframe component (154, 164) does not interfere with the control region (171, 172) of a subframe (170, 180) transmitted on an overlapping component carrier (130) by an uncoordinated second base unit (105). The wireless base unit (102) transmits the truncated subframe component (154, 164) and also transmits truncation time period information within a control region (151, 161) of an anchor carrier (110). A remote terminal (104, 108) that supports carrier aggregation searches a control region (151, 161) of a subframe (150, 160) transmitted on the anchor carrier (110) for truncation information and uses the truncation information to determine a boundary of a data region in a subframe component (154, 164) received on the additional component carrier (120).

    摘要: Various methods and apparatuses for receiving a control channel involve a communication device monitoring a first control and receiving information from a network regarding the configuration of a second control channel. The communication device receives an uplink grant from the network; transmits a message to the network, in which the message indicates to the network that the communication device is capable of monitoring the second control channel. The communication device monitors the second control channel based on the configuration information receiving via the first control channel.

    摘要: A wireless communication user terminal obtains uplink access configuration information on a physical downlink control channel (PDCCH) addressed to a plurality of user terminals by processing the PDCCH based on a first system information received from a base station on a physical broadcast channel (PBCH) and based on synchronization information. The terminal sends a signature waveform based on the uplink access configuration information, prior to receiving system information in addition to the first system information, whereby the signature waveform enables the base station to transition from a relatively low power operating mode to a relatively high power operating mode.

    摘要: Methods and apparatus' of determining radio link quality are disclosed. According to various implementations, information indicating the time-frequency blocks to be monitored by a UE to enable the UE to locate a control channel is determined. The UE receives configuration information regarding resources used by a channel state information reference signal. It also receives configuration information regarding an interference measurement resource, as well as a channel state information reference signal. The channel state information reference signal uses the channel state information reference signal resources. A synchronization condition is determined based on the time frequency blocks to be monitored by the UE, the received channel state information reference signal and the interference measurement resource. The determined synchronization condition is sent to a higher layer.

    摘要: A method (400) and user equipment (106) monitor a radio link for a wireless communication terminal for an enhanced control channel. A processor (304) may acquire signaling configuring the user equipment to monitor for a first type of control channel, where the first type of control channel can be demodulated based on a first type of reference signal. The processor may receive a second type of reference signal in at least one or more resource block set, where the second type of reference signal can be distinct from the first type of reference signal. The processor may estimate a synchronization condition based on the received second type of reference signal and at least one attribute of the control channel. The processor may send an output from a current layer to a higher layer based on the estimated synchronization condition.
