摘要:
A wireless communication terminal including a controller coupled to a transceiver, configured to receive a first and second control messages on an anchor carrier is disclosed. The first control message includes a resource assignment for the anchor carrier and the second control message is associated with a set of component carriers that are distinct from the anchor carrier. The controller determines a resource assignment for at least one component carrier in the set of component carriers using both the first and the second control messages.
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.

A wireless communication terminal and method for determining a number of Physical Hybrid ARQ Indicator Channel (PHICH) groups (N) in the downlink subframe based on a first parameter, a second parameter and a determined cyclic prefix (CP) duration, wherein the first parameter indicates a downlink system bandwidth in terms of a number of resource blocks and the second parameter indicates a scaling factor. The terminal receives downlink control signaling in a set of resource elements in the subframe, wherein the set of resource elements is determined based partly on the number of PHICH groups (N).

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.

A user equipment (UE) receives a signal comprising multiple resource blocks and configured for receiving a subframe comprising multiple time-frequency resources, the time-frequency resources comprising at least two control channel candidates. The UE determines a first control channel candidate of the at least two control channel candidates in the subframe, determines a first antenna port (AP) associated with the first control channel candidate, decodes the first control channel candidate based on the first AP, determines a second control channel candidate of the at least two control channel candidates in the subframe, determines a second AP associated with the second control channel candidate, and decodes the second control channel candidate based on the second AP, wherein the AP used for decoding the first control channel candidate is distinct from the AP used for decoding the second control channel candidate.

摘要:
A method in a wireless communication terminal including monitoring a terminal specific search space of a first Component Carrier (CC) from a base unit, wherein the search space corresponds to a set of Physical Downlink Control CHannel (PDCCH) candidates monitored by the terminal for PDCCH messages, and receiving an activation message on the first CC, wherein the activation message activates at least one additional CC. The size of the search space monitored by the terminal after receiving the activation message is greater than the size of the search space monitored before receiving the activation message.
