摘要： The present invention relates to radio communication in a cellular network and in particular to the sharing of a frequency spectrum with another network. The object is to enable robust communication in the shared band. The solution is to allocate a third band for communication in a cell. A L1/L2 control channel may be transmitted in the third band only, whereas data can be transmitted in the shared band. The L1/L2 control channel support the data communication in the shared band. The invention relates to a method and a radio base station.

摘要： The invention provides a scheduling of data blocks on multiple data carriers (310, 320) and a selection of data carrier to listen to. A transmitting unit (200-1) simultaneously transmits, during a communication session with at least one participating receiving unit (100), at least a first data block (14) on a first data carrier (310) and a second data block (22) on a second data carrier (320). The receiving unit (100) selects which of these data carriers (310), 320) to listen to, i.e. whether to receive the first (14) or second (22) data block, based on a reception quality of a previously received data block (12). Furthermore, at least one of the first (14) and second (22) data block is based on information common to the data block (14; 22) and the previous data block (12), e.g. the first (14) or second (22) data block could be re-transmitted version of the previous block (12).

摘要： A method implemented in a user terminal (20) for performing a random access procedure is presented. The method comprises transmitting a first random access request message including a random access preamble to a radio base station (18) using a random access channel, RACH, radio resource and receiving a second random access response message from the radio base station (18). The second random access response message indicates a timing change, an identified radio resource of an uplink shared channel, UL-SCH, and a temporary user terminal identity. The method also comprises adjusting a timing at the user terminal (20) for transmitting signals to the radio base station (18) based on the timing change indicated in the second random access response message and, based on the adjusted timing, transmitting a third message to the radio base station (18) over the identified radio resource of the uplink shared channel. The third message includes a user terminal identity that was assigned to the user terminal before the random access procedure is scrambled using a cell-associated scrambling sequence that is not terminal-specific. Further still, the method comprises receiving a fourth contention resolution message from the radio base station (18) to complete the random access procedure.

摘要： The technology described in this case facilitates random access by a user terminal with a radio base station. A user terminal determines one of a first type of uplink scrambling sequences and generates a random access message using the determined one of the first type of uplink scrambling sequences. The random access message is transmitted to the base station. The user terminal receives from the base station a second, different type of uplink scrambling sequence and uses it for subsequent communication with the radio base station. For example, the first uplink scrambling sequences may be specifically associated with the radio base station's cell area or a random access radio channel associated with the radio base station, but they are not specifically assigned to any user terminal, and the second uplink scrambling sequence may be selected from a second set of uplink scrambling sequences specifically assignable to individual user terminals.

摘要： The invention discloses a method (400) for use in a first node (110) in a wireless access communication system (100). According to the method, the first node controls (405) traffic to and from users, UEs (120), within a certain area in the system, a cell, and the first node is equipped (410) with a plurality of transmit antennas (111,113). The first node can employ (415) a variety of multi antenna transmit modes for down link transmissions, i.e. transmissions to the UEs, and the first node can carry (420) out a so called Random Access (RA) procedure with UEs which do not have a dedicated up link resource, i.e. a resource to the eNodeB. According to the method, one and the same down link multi antenna transmit mode is used by the first node during the RA procedure.

摘要翻译：在这种情况下描述的技术有助于用无线电基站的用户终端的随机接入。用户终端确定第一类型的上行链路扰频序列中的一个，并使用所确定的第一类型的上行链路扰频序列来生成随机接入消息。随机接入消息被发送到基站。用户终端从基站接收第二种不同类型的上行加扰序列，并将其用于与无线基站的后续通信。例如，第一上行链路扰频序列可以与无线基站的小区区域或与无线基站相关联的随机接入无线信道具体地关联，但是并不特别地分配给任何用户终端，第二上行链路加扰序列可以从专用于各个用户终端的第二组上行链路扰频序列中选择。
