Abstract: Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In some aspects, a user equipment (UE) receives a data transmission on at least one component carrier (CC) in a plurality of configured CCs. The UE determines acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission and determines an uplink channel for sending the ACK/NACK information. When the ACK/NACK information is sent on a PUCCH, the UE may perform power control based on which CCs in the plurality of configured CCs data is received. When the ACK/NACK information is sent on a PUSCH, the UE may determine a number of resource elements based on its CC configuration.

Abstract: Certain aspects of the present disclosure relate to mapping bearer data in multiple connectivity configurations. A first portion of first data available for transmission over a first type bearer can be mapped to first uplink resources granted from a first base station, wherein the first type bearer is configured for transmission using the first base station and a second base station. Then, it can be determined whether a remaining portion of the first uplink resources are available after mapping the first portion of first data. If so, second data from a second type bearer can be mapped to at least a first portion of the remaining portion of the first uplink resources based at least in part on determining that the remaining portion of the first uplink resources are available. This can ensure, in some cases, that data for the second type bearer is also transmitted over the uplink resources.

Abstract: Channel state information (CSI) feedback in long term evolution (LTE) and LTE-Advanced (LTE-A) networks including unlicensed spectrum is disclosed in which a base station obtains clear channel assessment (CCA) result information from neighboring base stations, either directly or by determining such results from measurement or reports from user equipment (UE) served by the base station.

Abstract: Methods and apparatus for wireless communication are described. A method may include receiving at a user equipment (UE) a number of allocated interlaces for an uplink transmission over a shared spectrum, each of which may include a plurality of non-contiguous resource blocks (RB) of the shared spectrum. In some cases, the number of allocated interlaces is unsupported by joint interlace precoding hardware of the UE and the allocated interlaces may be partitioned into subsets of interlaces which may be a size supported by the joint interlace precoding hardware. Reference signals may be generated for the RBs of the allocated interlaces according to a reference signal sequence based on an ordering of the RBs for the allocated interlaces within the shared spectrum.

Abstract: Techniques are described for channel access in a radio frequency spectrum band shared by a number of asynchronous operators. One or more clear channel assessment (CCA) procedures may be used to contend for one or more transmission periods in the radio frequency spectrum band. When the contention is won for one or more transmission periods, a determination may be made as to whether the a number of transmission periods for which contention has been won is equal to or greater than a threshold number of consecutive transmission periods. If the number of transmission periods for which contention has been won is at or above the threshold number, occupancy of the radio frequency spectrum band may be relinquished for a period of time, in order to allow another operator to access the radio frequency spectrum band.

Abstract: Techniques are described for wireless communications utilizing multiple clear channel assessment (CCA) procedures for access to a radio frequency spectrum band. A first CCA procedure is performed to determine availability of the radio frequency spectrum band and to contend for use of the radio frequency spectrum band among a number of coordinated operators transmitting on the radio frequency spectrum band. A successful first CCA procedure results in winning the contention for the radio frequency spectrum band for a transmission period that is coordinated among the number of coordinated operators. Upon the successful first CCA procedure, a second CCA procedure is performed during a discontinuous transmission (DTX) period in the transmission period to determine continued availability of the radio frequency spectrum band. The timing of the DTX periods is determined based on timing of radio transmissions having priority use of the radio frequency spectrum band.

Abstract: Uplink control channel management is disclosed for LTE/LTE-A communication systems with unlicensed spectrum in which two or more physical resource blocks (PRBs) are allocated for uplink control channel transmission. The uplink control information (UCI) payload may be determined based on clear channel assessment (CCA) information associated with carriers scheduled for transmission of the UCI data. With the UCI payload determined, two or more uplink control channel messages may be generated according to at least one control channel format, wherein uplink control channel messages include the UCI payload. These generated uplink control channel messages may then be transmitted over the allocated PRBs.

Abstract: Methods, systems, devices, and apparatuses are described for wireless communications.

A group hybrid automatic repeat request (HARQ) feedback message for a plurality of data subframes including at least one of the data subframes in the set of one or more data subframes may then be received over the unlicensed spectrum, from the UE, during the transmission period.

Abstract: A control scheme using packet headers allows GSM EDGE Radio Access Network (GERAN) systems to increase spectral efficiency through multiplexing techniques, such as superposition coding, multi-user packet transmission, joint detection, and/or joint decoding. A fast feedback scheme for GERAN allows Voice over Internet Protocol (VoIP) frames to be transmitted over GERAN air interfaces without excessive feedback latency. As a result, Hybrid Automatic Repeat-reQuest (H-ARQ) acknowledgements may be timely provided for end-to-end VoIP calls that traverse GERAN air interfaces. Additionally, Incremental Redundancy H-ARQ and link quality feedback latencies are decreased.
