摘要:
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, the method comprising the steps of identifying the number of carriers used to communicate with the access device, based on the number of carriers used to communicate with the access device, identifying a number of CCE subset candidates to decode and decoding up to the identified number of CCE subset candidates in an attempt to identify the resource grant.

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.

A method for processing a control channel at a user agent (UA) to identify at least one of an uplink and a downlink resource grant within a wireless communication system wherein resource grants are specified by control channel element (CCE) subsets wherein each CCE subset is a control channel candidate, wherein the control channel is used for a plurality C of carriers, the method comprising the steps of, at the user agent, for each of the C carriers, (i) randomly identifying a UA specific search space including a control channel candidate subset for the carrier and (ii) attempting to decode each of the control channel candidates in the UA specific search space to identify at least one of an uplink and a downlink grant associated with the carrier.
摘要:
A method for processing a control channel at a user agent (UA) to identify at least one of an uplink and a downlink resource grant within a wireless communication system wherein resource grants are received using control channel element (CCE) subsets wherein each CCE subset is a control channel candidate, wherein the UA is configured to decode up to M control channel candidates per time period for single carrier operation, the method comprising the steps of, at the user agent, identifying N control channel candidates that are distributed among C carriers wherein N is less than M×C, attempting to decode each of the N identified control channel candidates to identify at least one of an uplink and a downlink resource grant and where a control channel candidate is successfully decoded, using the one of the uplink grant and the downlink grant to facilitate communication.

A method and system for achieving a link budget improvement in a diverse OFDM radio system by addressing the timing misalignment issue that can occur due to the differences in propagation time in signals between mobile stations and Radio Access Nodes. Timing misalignment is shared or split between the primary path to a primary Radio Access Node and a diverse path to a diverse Radio Access Node. The relative timing offsets between mobile stations are adjusted, the mobile stations are grouped into zones using a variety of different grouping techniques, and the transmission for each mobile station is scheduled, using one or more of a variety of scheduling techniques.

A radio link protocol for a communications system ensures that delivery of Internet protocol data packets occurs within a set delay bound for the packets, in order to satisfy specified quality of service levels. Data packets arriving at a transmitter are subdivided into data blocks. As each block is transmitted, the transmitter starts an associated acknowledgement timer. The timer is turned off, before it expires, if the transmitter timely receives from a receiver a message informing the transmitter that the associated block was successfully received. If such message is not received, the timer expires and the transmitter sends an acknowledgement request signal to the receiver and starts an associated panic timer. The panic timer is turned off, before it expires, if the transmitter subsequently timely receives a message that the associated block was successfully received. If such message not received, the panic timer expires and the transmitter sends one of more copies of the corresponding block to the receiver before occurrence of the delay bound. If the transmitter receives a negative acknowledgement message from the receiver, that a block is missing or corrupted, the transmitter retransmits a copy of the block to the receiver. To reduce messaging traffic, the transmitter cancels acknowledgement and panic timers based upon information contained in negative acknowledgement messages, and the receiver can periodically send acknowledgement messages to inform the transmitter of successfully received blocks.
