Abstract
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.
Claims20
A method for a communication device to handover from a first cell to a second cell, the method comprising:
- receiving, by a communication device, a handover message indicating that the communication device is to handover from the first cell to the second cell, the first and second cells operating on the same carrier frequency, wherein the handover message includes information regarding one or more of:
- information regarding time-frequency resources of a control channel of the second cell, wherein the frequency span of the time-frequency resources is smaller than the transmission bandwidth configuration of the second cell,
- an identification of a set of antenna ports to be used to communicate via a control channel of the second cell, and
- information regarding energy per resource element of a control channel of the second cell;
- performing, by the communication device, a handover from the first cell to the second cell;
- and
- receiving, via the control channel of the second cell by the communication device, indication of resources for at least one of downlink and uplink transmissions.
A system for performing handovers from a first cell to a second cell, the system comprising a communication device configured to:
- receive a handover message indicating that the communication device is to handover from the first cell to the second cell, the first and second cells operating on the same carrier frequency, wherein the handover message includes information regarding one or more of:
- information regarding time-frequency resources of a control channel of the second cell, wherein the frequency span of the time-frequency resources is smaller than the transmission bandwidth configuration of the second cell,
- an identification of a set of antenna ports to be used to communicate via a control channel of the second cell, and
- information regarding energy per resource element of a control channel of the second cell;
- perform a handover from the first cell to the second cell;
- and
- receive, via the control channel of the second cell, indication of resources for at least one of downlink and uplink transmissions.
A non-transitory, tangible machine readable medium on which instructions are stored, the instructions, when executed by a processor cause the processor to perform a method for a communication device to handover from a first cell to a second cell, the method comprising:
- receiving a handover message indicating that the communication device is to handover from the first cell to the second cell, the first and second cells operating on the same carrier frequency, wherein the handover message includes information regarding one or more of:
- information regarding time-frequency resources of a control channel of the second cell, wherein the frequency span of the time-frequency resources is smaller than the transmission bandwidth configuration of the second cell,
- an identification of a set of antenna ports to be used to communicate via a control channel of the second cell, and
- information regarding energy per resource element of a control channel of the second cell;
- performing a handover from the first cell to the second cell;
- and
- receiving, via the control channel of the second cell, indication of resources for at least one of downlink and uplink transmissions.
