摘要： Mechanisms for efficient transmission of large amount of download data from a base station to a user equipment in a multi-carrier that minimizes power consumption on the user equipment are described. When multiple component carriers are to be used to transmit the download data, the base station informs the user equipment. The base station transmits on the anchor carriers without wait after informing the user equipment and transmits on the non-anchor carriers after waiting a predetermined delay. The predetermined delay provides time to allow the user equipment to activate the receiving resources and be ready to receive the download data over the non-anchor carriers. In this manner, the user equipment can be in a power conservation mode and activate the receiver resources only when needed.

摘要： It is disclosed a network node, a communication device and methods therein, for scheduling of uplink resources in multiple time instances and transmitting in accordance with the scheduled UL resources. By including an indicator in an UL grant comprising an UL resource allocation, the indicator indicates that, for at least one UL time instance of the multiple time instances, at least one UL resource is excluded from, or added to, the UL resource allocation of the UL grant.

摘要： The available transmission resources on a downlink-shared channel are divided into resource blocks, each resource block comprising a predetermined number of sub-carriers during a predetermined time period. The resource blocks are subdivided into localized resource blocks and distributed resource blocks. A user requiring sufficient resources can be allocated a plurality of said localized resource blocks. A user who would require only a small number of said localized resource blocks can instead be allocated subunits of a plurality of said distributed resource blocks.

摘要： A guard period for switching between uplink and downlink subframes is created by shortening an uplink subframe, i.e., by not transmitting during one or more symbol intervals at the beginning of the subframe interval. A grant message includes signaling indicating when a shortened subframe should be transmitted. An example method is implemented in a first wireless node configured to transmit data in transmit subframes occurring at defined subframe intervals and having a predetermined number of symbol intervals. This example method includes determining (1620) that a transmit subframe is to be shortened, relative to the predetermined number of symbol intervals and, in response to this determination, shortening (1630) transmission of the transmit subframe by not transmitting during a beginning portion of the subframe interval for the transmit subframe and transmitting during the remainder of the subframe interval.

摘要： The teachings presents a method 10 performed in a network node 2, the network node 2 controlling a first and a second antenna point 3, 4. The network node 2 uses the same random access resources for the first and the second antenna points 3, 4. The method 10 comprises: detecting 11 a specific random access preamble received on a random access resource at the first antenna point 3 and on the same random access resource at the second antenna point 4; and scheduling 12 a transmission of a random access response to the random access preamble received at the first antenna point 3 and a transmission of a random access response to the random access preamble received at the second antenna point 4, the random access responses being scheduled separated in time and/or space. The teachings also presents corresponding devices.

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： A network node (310) comprising a radio frequency communications interface (230) and a controller (210), said network node (310) being configured to service at least one first radio frequency communication device (320) being configured for both network communication and for device-to-device communication with a second radio frequency communication device (325), wherein said controller (210) is configured to determine if a restriction of a scheduling policy is necessary for said first radio frequency communication device (320), select a scheduling policy accordingly. The controller is further configured to allocate communication resources according to said selected scheduling policy to said first radio frequency communication device (320). The scheduling policy is one which enables simultaneous network communication and device-to-device communication in said same transmission time interval (A, B, C, D, E) or one which enables either network communication or device-to-device communication in said same transmission time interval.

摘要： A guard period for switching between uplink and downlink subframes is created by shortening a downlink subframe, i.e., by not transmitting during one or more symbol intervals at the end of the subframe. A grant message includes signaling indicating when a shortened subframe is being transmitted. An example method is implemented in a receiving node configured to receive data from a transmitting node in subframes having a predetermined number of symbol intervals. In an LTE system, this receiving node may be a UE, and the subframes are downlink subframes. This example method includes determining 1120 that a received subframe is to be shortened, relative to the predetermined number of symbol intervals and, in response to this determination, disregarding 1130 a last part of the received subframe by disregarding one or more symbols at the end of the received subframe when processing the received subframe.

摘要： Systems and methods are disclosed for transmission and reception of an uplink grant during a gap created in radio resources assigned by a previous multiple Transmit Time Interval (multi-TTI) uplink grant in a system operating according to a Time Division Duplexing (TDD) scheme. In one embodiment, a method of operation of a radio network node in a cellular communications network is provided. The method includes transmitting a first uplink grant that assigns radio resources for a multi-TTI uplink transmission, and transmitting a second uplink grant during a gap in the radio resources assigned by the first uplink grant. In one embodiment, by utilizing the gap to transmit the second uplink grant, uplink radio resources assigned for uplink transmission can be maximized, which is particularly beneficial in high uplink traffic conditions.
