In an access device associated with a first network cell, a method for enabling user equipment (UE) to obtain a service unavailable through the first network cell includes receiving a request for the UE to access the service, and identifying, in a message to the UE, a plurality of second network cells providing the service.

Method for accessing a service unavailable through a network cell

A method for reporting power headroom-related information for a plurality of aggregated carriers. The method includes reporting in a bitmap the power headroom-related information for a number of the aggregated carriers that is less than or equal to the total number of aggregated carriers, wherein the power headroom-related information is one of a power headroom for at least one of the aggregated carriers and a path loss for at least one of the aggregated carriers.

Reporting power headroom for aggregated carriers

A method for processing a control channel at a user agent (UA) to identify power control commands within a wireless communication system, the method comprising the steps of, at a user agent, monitoring for power control messages on a single carrier, decoding a message received on the single carrier to generate decoded information and using the decoded information to identify a power control command for each of at least first and second carriers.

System and method for reducing decoding for carrier power control

A method performed by user equipment (UE) includes receiving a request to access a service unavailable through a first network cell associated with the UE and informing a second network cell that the UE is requesting to obtain the service unavailable through the first network cell. The request may be received from a user of the UE or may be a paging message.

Systems, methods, and software can be used to process a control channel at a user agent (UA) within a wireless communication system. In some aspects, the method includes identifying one carrier as an anchor carrier andat least one otheranothercarrier as a non-anchor carrier;for each carrier: determining a location of a UA specific search space including one or more control channel candidates for the carrier based on a linear congruential random number; and attempting to decode each of the control channel candidates in the UA specific search space to identify at least one of an uplink or a downlink grant associated with the carrierand receiving information indicating a first number of control channel candidates for a first aggregation level for the anchor carrier and a second number of control channel candidates for the first aggregation level for the non-anchor carrier, wherein the first number of control channel candidates is different from the second number of control channel candidates.

System and method for determining a search space in carrier aggregation in LTE-A

Methods, devices, and systems for the transmission of information in a wireless communication system are disclosed. In one embodiment, a method for the transmission of information in a wireless communication system comprises receiving a downlink message, wherein the downlink message includes a first control channel element; determining a first index using the location of the first control channel element; determining a second index; determining a first orthogonal resource using the first index; determining a second orthogonal resource using the second index; spreading an uplink message using the first orthogonal resource to form a first spread signal; spreading the uplink message using a second orthogonal resource to form a second spread signal; transmitting the first spread signal using a first antenna; and transmitting the second spread signal using a second antenna.

Transmission of information in a wireless communication system

A method and system to signal transmission layers or dedicated reference signal ports to be used in a multiple input multiple output system, the method including providing a downlink control signal containing information for transmission layers or dedicated reference signal ports utilized, the dedicated reference signal ports being associated with the transmission layers; and using the information to demodulate data on each transmission layer.

Method and system for signaling transmission layers for single user and multi user MIMO

A method for processing a control channel at a user agent (UA) to identify at least one of an uplink and a downlink resource allocated by a resource grant within a multi-carrier communication system wherein resource grants are specified by control channel element (CCE) subset candidates wherein the carriers used for data transmission and reception are configured carriers, the method comprising the steps of receiving activation signals specifying active and deactivated carriers from among the configured carriers, for active carriers (i) identifying a number of CCE subset candidates to decode and (ii) decoding up to the identified number of CCE subset candidates in an attempt to identify the resource grant; and for deactivated carriers, ignoring CCE subset candidates associated with the deactivated carriers.

System and method for sharing a control channel for carrier aggregation

A system and method for permuting known and unknown message bits before encoding to provide a beneficial rearrangement of bits. Such a method can improve distance properties in the resulting subcode. In various embodiments, the structure of a beneficial rearrangement is dependent on the parameters of how known and unknown bits are grouped and on the specific type of code being used. Given these two parameters, the message bits can be rearranged to more efficiently leverage any apriori knowledge.
