摘要： The present invention relates to a scheduling apparatus (100) and a method for a cellular Time-Division Duplex (TDD) radio communication system (180). The apparatus comprises a storage unit configured for holding a database comprising topographical information concerning a geographical area covered by the communication system. The apparatus also comprises a position unit configured for obtaining information concerning a geographical position held by at least one of a first and a second radio communication device (120;160) of the communication system within said area. The apparatus further comprises a scheduling unit configured for allocating a communication time slot as an uplink time slot or a downlink time slot for radio communication between a first base station (110) and said first device (120) of the communication system. Whether the time slot is allocated as an uplink time slot or a downlink time slot is dependent on said position information and on said topographical information.

摘要： A communication system node transmits first control channel information on a control channel that extends over a first bandwidth of a radio frequency resource. The first control channel information is necessary to enable a first type of communication device, capable of receiving a signal having the first bandwidth, to establish a connection with a host cell. A MIB, occupying a second bandwidth-size part of the first bandwidth, is transmitted. The second bandwidth is smaller than the first bandwidth and is receivable by a second type of communication device having reduced receive bandwidth capabilities. The MIB has a first part comprising first part information necessary to enable the first type of communication device to establish the connection with the host cell, and a second part comprising second part information directly or indirectly enabling the second type of communication device to obtain parameters that enable connection establishment with the host cell.

摘要： A network node that serves a host cell in a cellular communication system transmits, at (a) first time interval(s), first control channel information on a control channel that extends over a first bandwidth of a radiofrequency spectrum. The first control channel communicates information necessary to enable a first type of communication device to receive data from the host cell. The first type of communication device can receive first bandwidth-wide signals. At (a) second time interval(s), second control channel information is transmitted on a second control channel of a first M-cell. The second control channel occupies a second bandwidth that is smaller than the first bandwidth. The second time interval(s) do(es) not coincide with any of the first time interval(s). A second type of communication device having reduced receive bandwidth capabilities compared to those of the first type of communication device is thereby made capable of being served by the node.

摘要： In one example of the teachings herein, a network base station (16, 18) includes one or more communication interfaces configured to send messages to a wireless communication device, and one or more processing circuits (36) operatively associated with the communication interface(s). The processing circuits(36) are configured to send a reconfiguration message to the device using an existing downlink control channel configuration for the device, which message indicates a new downlink control channel configuration for the device, and, during a window of control channel configuration ambiguity that arises for the device as a consequence of sending the reconfiguration message, send a control message to the device using both the existing and the new downlink control channel configurations. Such a method of operation advantageously avoids the delays that arise if new downlink control signaling towards the device (20) is deferred until receiving confirmation that the device (20) received the reconfiguration message.

摘要： In a mobile network, the transmission of downlink data blocks (303, 307) to one or more terminal devices (200, 210) is accomplished on the basis of a retransmission protocol with a first feedback time (F1) defining a time interval between transmission of a first data block (303) and transmission of a first feedback message (308) being different from a second feedback time (F2) defining a time interval between transmission of a second data block (307) and transmission of a second feedback message (309). The first feedback message (308) indicates whether the first data block (303) was successfully received, and the second feedback message (309) indicates whether the second data block (307) was successfully received. A base station (100) of the mobile network controls the terminal device (200, 210) to send the second feedback message (309) on other resources than used for transmission of the first feedback message (308).

摘要： The present disclosure relates to User Equipments, UEs or Machine Type Communication, MTC (104, 202, 302, 304, 700) devices and base stations (102, 204, 306, 600) and methods therein for adapting the allocating of random access resources to user equipments of a cell served by a base station. A method in a base station (102, 204, 306, 600) where each RA preamble group maps or corresponds to an uplink allocation size, comprises receiving a RA preamble from a UE in a cell served by the base station, the preamble indicating a requested resource allocation size for uplink transmission of UE data. Radio resource usage (S-348, 402) in the cell is monitored and a mapping between groups of RA preambles and uplink allocation sizes (S-356, 412) configured for the cell is adapted based on the monitored usage of radio resources. UEs or MTC devices are thus provided with an efficient means to have their UL allocation needs for transmission of user data in conjunction with step 3 of the Random Access procedure met.

摘要： The present invention relates to a method and a base station (14, 700)for load balancing in Semi-Persistent Scheduling, SPS transmission. The method can comprise to activate downlink or uplink SPS transmission for a User Equipment (12, step 204), and to obtain information about transmission load comprising SPS transmission or HARQ ACK/NACK responses to SPS transmissions, on a Physical Shared or Control Channel (steps 206; 402; 406; 502, 504, 508, 510). Based on the obtained information it is determined for which subframe within aduration of T subframes, the transmission load comprising SPS transmission or HARQ ACK/NACK response to SPS transmissions, on a Physical Shared Channel or on a Physical Control Channel is the lowest within the duration of T subframes (steps 208; 404; 408; 506, 512, 514). SPS transmission is then scheduled to be valid in the determined subframe having the lowest SPS transmission load on the Physical Shared Channelor to be valid in a subframe causing the HARQ ACK/NACK responses to the SPS transmissions to be transmitted in the subframe having the lowest of HARQ ACK/NACK responses to the SPS transmissions, within the duration of T subframes (step 210).This load balancing provides a number of advantages comprising less postponed scheduling, less unused subframes and less collisions on said channels.
