摘要： A base station supports a contention-based channel and a schedule-based channel. If too many mobile terminals simultaneously transmit on the contention-based channel, the base station schedules retransmissions to those terminals on the schedule-based channel. Supporting this, a terminal transmits a user transmission on the contention-based channel that includes both a data transmission and a reference signal. The terminal derives this reference signal by selecting one of a plurality of cyclic shifts (CSs). Correspondingly, the base station receives the user transmission and can determine the selected CS even if it is unable to demodulate the data transmission. The base station then determines a retransmission identifier (RTI) mapped to that CS, according to a mapping between CSs and RTIs, and sends scheduling information for any needed retransmission to the terminal by addressing that information to the RTI. Meanwhile, the terminal knows this mapping and monitors for scheduling information addressed to that RTI.

摘要： A radio communication system and a method for assigning a short-lived Cell Radio Network Temporary Identifier, “CRNTI”, to a first user equipment performing random access to a radio network node are provided. The radio communication system registers the first user equipment as connected to the radio network node. A message for synchronizing the radio network node and the first user equipment with respect to the first time period is transferred. After the first time period has elapsed, the radio communication system maintains the first user equipment connected to the radio network node, and allows the short-lived CRNTI to be assigned to a second user equipment.

摘要： Collision mitigation for scheduling requests, SRs, on the physical uplink control channel, PUCCH, in Long Term Evolution, LTE, radiocommunication systems is described. Various types of SR collision mitigation information can be transmitted from a base station eNodeB (32) to a user equipment, UE(36). The UE can use the collision mitigation information to determine how to transmit its SRs. The network or base station (32) can use its knowledge of the SR collision mitigation information sent to various UEs (36) (and/or additional information) to resolve SR collisions on the uplink.

摘要： A node (100; 300) of a mobile network is responsible for scheduling transmissions of data blocks between the mobile network and a terminal device (200, 200′). The node (100; 300) may for example be a base station (100) or a control node (300) of the mobile network. The node (100; 300) determines a processing time required by the terminal device (200; 200′) for processing signals for transmission of one of the data blocks. The processing time is determined from a plurality of supported processing times. On the basis of the determined processing time, the node (100; 300) schedules the transmission of the data block. The terminal device (200, 200′) may provide control data for determining the processing time to the node (100; 300).

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.
