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： Systems and methods relating to coexistence of a cellular communications network technology (e.g., Long Term Evolution (LTE)) and another wireless technology (e.g., WiFi) in a shared unlicensed spectrum are disclosed. In particular, the present disclosure provides systems and methods that mitigate or avoid grabbing of an unlicensed, or shared, frequency band utilized by a wireless communications network node by a node of another wireless technology that operates according to a listen-before-talk scheme.

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： According to some embodiments, a method in a wireless network element of transmitting a transport block comprises determining a modulation coding scheme for a transmission of the transport block; determining a category type of a wireless device that will transmit or receive the transport block; determining, using the category type of the wireless device, an encoding soft buffer size (NIR) for the transport block; adjusting, using the modulation coding scheme. the encoding soft buffer size (NIR) by a factor (KH); encoding the transport block according to the determined modulation coding scheme and the adjusted encoding soft buffer size; and transmitting the transport block. In particular embodiments, the determined modulation coding scheme is 256 Quadrature Amplitude Modulation (256 QAM) and the factor (KH) is 4/3.

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.

摘要： In one aspect, the teachings herein provide a method and apparatus for extending certain HARQ feedback procedures introduced in LTE Rel-10, which were defined for CA configurations involving TDD serving cells of the same UL/DL configuration, to the new, more complex CA configurations introduced in Rel-11, which involve the aggregation of interband TDD serving cells with differing UL/DL configurations. Such reuse enables reliant and efficient HARQ feedback signaling in LTE Rel-11, without substantially increasing the specification or implementation complexity of HARQ feedback signaling in LTE Rel-11, despite the decidedly more complex CA configurations introduced in LTE Rel-11.

摘要： A first and a second radio communication device and a respective method performed thereby for communicating between the first and the second radio communication device are provided. The method in the first radio communication device comprises transmitting (210), on an unlicensed frequency band, to at least the second radio communication device, an indication of a duration of a guard period, wherein an upcoming data transmission is to be performed to the second radio communication device after the expiration of the guard period. The method further comprises during the guard period, sending and/or receiving (220) information to/from at least one other radio communication device, the other communication device being the second radio communication device or a third communication device.
