Abstract: Methods and apparatuses are described in which an unlicensed spectrum is used for Long Term Evolution (LTE) communications. A method by a base station includes transmitting an RTS signal in an unlicensed spectrum or a V-RTS signal in a licensed spectrum, addressed to a set of UEs, and transmitting a CTS-to-self signal in the unlicensed spectrum, wherein when the V-RTS signal is transmitted, the CTS-to-self signal is transmitted along with the transmission of the V-RTS signal.

Abstract: Techniques to support fast state transition by a user equipment (UE) are described. The UE may operate in a first state (e.g., a CELL_PCH state) in which the UE does not transmit or receive user data. The UE may receive a paging message carrying first configuration information. The UE may transition from the first state to a second state (e.g., a CELL_DCH state) in response to receiving the paging message. The UE may determine a set of communication parameters based on the first configuration information received from the paging message and second configuration information stored at the UE. The UE may then exchange user data based on the set of communication parameters. The UE may use default values for some parameters in order to reduce the amount of first configuration information to send in the paging message.

Abstract: Techniques for accessing a wireless communication system are described. A user equipment (UE) sends a random access preamble for system access. The random access preamble may include a random identifier (ID), a channel quality indicator (CQI), etc. The UE may randomly select the 5 random ID or may be assigned this random ID. The UE receives a random access response from a base station. The random access response may include control channel resources (e.g., CQI and PC resources), uplink resources, and/or control information (e.g., timing advance and PC correction) for the UE. The random access response may be sent in two parts using two messages. A first message may be sent on a control channel and may include identification information and possibly other 10 information. A second message may be sent on a shared data channel and may include remaining information for the random access response. co z U) o C -(D 0 (D) 5D wU a) c L. C> CD o 0 Zu E E C-) _0 0 Cl.,

Abstract: Embodiments disclosed herein address the need in the art for efficient management of grant, acknowledgement, and rate control channels. In one aspect, a list associated with a first station is generated or stored, the list comprising zero or more identifiers, each identifier identifying one of a plurality of second stations for sending a message to the first station. In another aspect, sets of lists for one or more first stations are generated or stored. In yet another aspect, the messages may be acknowledgements, rate control commands, or grants. In yet another aspect, messages comprising one or more identifiers in the list are generated. Various other aspects are also presented. These aspects have the benefit of reduced overhead while managing grant, acknowledgment and rate control messaging for one or more remote stations.

Abstract: UE that are able to cancel interference from CRS, a PDSCH, a PDCCH, or a PCFICH may do so without explicitly signaling the capability to the serving eNB. The serving eNB may transmit to the UE a plurality of cell identifiers to indicate from which cells interference should be canceled. The UE receives CRS, PDSCH, PDCCH, or PCFICH from the serving eNB and cancels CRS, PDSCH, PDCCH, or PCFICH interference, respectively from the signal received from the eNB. The UE cancels the interference from the cells that correspond to the cell identifiers. The UE may then transmit a report to the eNB with a quality measurement without the interference.

Abstract: Techniques for dynamically assigning acknowledgement (ACK) resource to a user equipment (UE) are described. For dynamic scheduling, a scheduling message may be used to send scheduling information for a single transmission of data. For semi-persistent assignment for multiple 5 transmissions of data. In an aspect, at least one field of a scheduling message, which is normally used to carry scheduling information for dynamic scheduling, may be re-used to carry and ACK resource assignment for semi-persistent scheduling. In one design, a UE may receive a scheduling message carrying a semi-persistent assignment and may obtain an assignment of ACK resource from the at least one field of the scheduling message. The UE may receive a transmission of data sent in accordance 0 with the semi-persistent assignment, determine AK information for the transmission of data, and send the ACK information with the ACK resource.

Abstract: A method and apparatuses for wireless communications are described. The method comprises determining (902), at a first base station (110a...z), a measurement gap (702) associated with a second base station (110a...z) for an inter-frequency or an inter-RAT, radio access technology, radio resource measurement, generating (904), at the first base station (110a...z), resource partitioning information, RPI, with at least one subframe designated for radio resource measurements of the first base station (110a...z) and transmitting (906) subframes from the first base station (110a...z) according to the RPI, wherein the at least one subframe designated for radio resource measurements of the first base station (110a...z) falls within the measurement gap (702) associated with the second base station (110a...z).

The UE may receive a transmission of data sent in accordance with the semi-persistent assignment, determine ACK information for the transmission of data, and send the ACK information with the ACK resource.Figure 3
