摘要:
Methods for performing handovers and addition of carriers during carrier aggregation operation are described. A mobile station can indicate failure to perform downlink synchronization to some but not all cells of a target eNB, in response to a handover command. The mobile station can activate carriers based on various combinations of transmission of random access preambles, reception of random access response messages and transmission of handover complete messages. A base station can activate carriers based on various combinations of reception of random access preambles, transmission of random access response messages and reception of handover complete messages.

Methods for performing change of primary cell during carrier aggregation operation are described. A mobile station (MS) receives a message to change a primary cell and to perform a random access communication with a new primary cell. Upon receiving a random access response message from the new primary cell, the MS starts transmitting a control channel to the new primary cell. In one embodiment, the MS releases the configuration of an uplink control channel and transmits uplink control information through an uplink shared channel. Upon completion of the primary cell change procedure, the MS starts transmission of an uplink control channel to the new primary cell.

摘要:
A method in a wireless communication terminal supports aggregated carrier access. The terminal is configured to transmit a power headroom report of a first type, determine that a condition for transmission of a power headroom report of a second type is satisfied, and transmits a power headroom report of the second type. In other embodiments, essential power headroom reports are prioritized over non-essential power headroom reports.

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.

A mobile station is disclosed wherein the mobile station determines interference by assessing one or more frames in a first periodic sequence of frames relative to a reference and, in response to the assessment, monitors transmissions from a base station for paging signals during a second periodic sequence of frames, wherein the second periodic sequence of frames is offset from the first periodic sequence of frames by a predetermined amount.

摘要:
A method and apparatus for power allocation for overlapping transmissions is provided herein. During operation, user equipment will determine if transmissions to a single base station, on various frequencies, will be overlapping. If so, a determination is made to back off the power for at least one transmission on one frequency.
