摘要： Systems and methods enabling uplink power sharing for dual connectivity are disclosed. Embodiments are described herein in which a maximum Uplink (UL) power on each link is configured statically, semi-statically, or dynamically. In general, regardless of the embodiment, uplink power for uplink transmissions from a wireless device on two simultaneous links is controlled such that the total uplink power does not exceeds a maximum UL transmission power level while, in some embodiments, taking into account priorities of the two links and/or priorities of various uplink channels transmitted by the wireless device on the two links. Notably, while the embodiments described herein focus on dual connectivity, the embodiments described herein can easily be extended to any number of two or more simultaneous links.

摘要： Techniques for supporting both localized and frequency-distributed control channel messages in the same enhanced control channel region are disclosed. An example method begins with receiving (2010) a downlink signal comprising an enhanced control region consisting of at least two sets of physical resource block (PRB) pairs. The method continues with the forming (2020) of one or more distributed enhanced control-channel elements (eCCEs) from a first set of PRB pairs by aggregating physical layer building blocks from multiple PRB pairs to form each distributed eCCE. One or more localized eCCEs are formed (2030) from a second set of PRB pairs by aggregating physical layer building blocks such that each of the localized eCCEs is formed from physical layer building blocks from within a single PRB pair of the second set. Control channel message candidates are formed (2050) from the distributed eCCEs and localized eCCEs, respectively, and decoded (2060).

摘要： A base station (20A) is configured to transmit user data to a wireless device (16A) upon a first carrier (22). The base station (20A) identifies, from a set of transmission resources that is nominally allocated for transmission of user data upon the first carrier (22), a subset of transmission resources that is also nominally allocated for transmission of a reference or control signal either by the base station (20A) upon a second carrier (24) or by a neighboring base station (20B) upon the first carrier (22). The base station (20A) selectively transmits user data to the wireless device (16A) upon the first carrier (22) exclusive of this identified subset of transmission resources. The device (16A) in some embodiments obtains information indicating that the base station (20A) is selectively transmitting user data upon the first carrier (22) exclusive of the subset in this way. Based on this information, the device (16A) recovers user data received upon the first carrier (22) exclusive of the subset of transmission resources.

摘要： According to some embodiments, a method of performing a Hybrid Automatic Repeat Request (HARQ) process comprises receiving, by a wireless device executing a HARQ process, a first transport block encoded according to a category type of the wireless device and a first modulation coding scheme; decoding, by the HARQ process, the first transport block using a number of soft bits N; receiving, by the wireless network element, a second transport block encoded according to the equipment type and a second modulation coding scheme different from the first modulation coding scheme; and decoding, by the HARQ process, the second transport block using the number of soft bits N.

摘要： The embodiments herein relate to method in a network node (301) for handling scheduling of a wireless device (305) in a communications network (300). The network node (301) is adapted to communicate with the wireless device (305) over a radio channel (310). The network node (301) dynamically allocates a set of non-consecutive subframes in which the network node (301) is to transmit data to the wireless device (305) or receive data from the wireless device (305). The network node (301) transmits a multi-Time Transmission Interval, TTI, scheduling message to the wireless device (305), which multi-TTI scheduling message comprises information indicating the dynamically allocated non-consecutive subframes.

摘要： A system and method for determining a Physical Uplink Control Channel (PUCCH) power control parameter h(nCQI,nHARQ) for two Carrier Aggregated (CA) PUCCH formats—PUCCH format 3 and channel selection. The value of h(nCQI,nHARQ) may be based on only a linear function of nHARQ for both of the CA PUCCH formats. Based on the CA PUCCH format configured for the User Equipment (UE), the e-Node B (eNB) may instruct the UE to select or apply a specific linear function of nHARQ as a value for the power control parameter h(nCQI,nHARQ), so as to enable the UE to more accurately establish transmit power of its PUCCH signal. Values for another PUCCH power control parameter—ΔF_PUCCH(F)—are also provided for use with PUCCH format 3. A new offset parameter may be signaled for each PUCCH format that has transmit diversity configured

摘要： Coordination information for controlling base-station-to-base-station interference is transmitted from one radio network node (900) (e.g., an LTE eNodeB) to another, using certain parts of the TDD subframe. One example method, as might be implemented in a radio network node (900) such as an LTE eNodeB, includes the generating (1010) of a TDD coordination signal and the transmitting (1020) of the TDD coordination signal to one or more other radio network nodes. In some embodiments, the coordination signal is transmitted in a guard period of a special subframe at the target node. In others, the coordination signal is transmitted in another interval during which the receiving node is not transmitting, such as in uplink subframe for the receiving node, an uplink portion of a special subframe at the receiving node, or in a downlink subframe or downlink portion of a special subframe during which the receiving node is not transmitting.

摘要： Systems and methods relating to detecting one or more characteristics (e.g., a carrier type or a carrier mode) of a carrier signal transmitted by a radio access node of a cellular communications network are disclosed. In one embodiment, a method of operation of a wireless device includes receiving a carrier signal transmitted by a radio access node and detecting, in the carrier signal, a first physical signal that primarily supports synchronization and cell identification and a second physical signal that supports a functionality other than synchronization and cell identification. A time-domain spacing between the first and second physical signals is a function of a characteristic of the carrier signal. The method further includes determining a characteristic of the carrier signal based on a time-domain spacing between the first and second physical signals detected in the carrier signal.
