    摘要： In one aspect of the disclosed teachings, associating a plurality of contention-based uplink grants with a range of uplink resource blocks allows one contention-based uplink grant message to signal the entire plurality of grants. As an example in the LTE context, the signaling load on the PDCCH is reduced by using a single contention-based uplink grant message to signal a plurality of contention-based uplink grants. The message indicates an allocated set of uplink resource blocks and the number of separate uplink resource grants represented by the set is known or signaled, such that user terminals recognize that separate subsets of uplink resource blocks within the set each correspond to a separate contention-based uplink grant. Information included in the contention-based uplink grant message, or otherwise signaled can be used to control the probability at which the user terminals attempt contention-based uplink transmissions and/or to control the MCS used for such transmissions.

    摘要： Method and arrangement in a serving base station for determining a binary value of information data received from a user equipment, by using a supportive likelihood value received from a supporting base station. The user equipment transmits information data to be received both by the serving base station and the supporting base station. The method comprises: decoding information data bits received from the user equipment into a first likelihood value, without determining a binary value for each bit of the information data, a supportive likelihood value of the information data bits transmitted from the user equipment is received from the supporting base station, which supportive likelihood value is based on a decoding of the information data bits performed in the supporting base station. The first likelihood value of the decoded information bits is combined with the received supportive likelihood value of the decoded information bits. Thus a binary value for each bit of the information data transmitted from the user equipment is determined, based on the combined first and supportive likelihood values.

    摘要： The present invention relates to a power control method in a wireless station and a wireless station implementing said method. A transmission power is selected (301) for transmission of a signal (e.g. a Request to Send control frame or a Clear to Send control frame) locally reserving a wireless medium for communication of data involving the wireless station based on Quality of Service requirements associated with said communication of data. Said signal is transmitted (302) at said selected transmission power.

    摘要： The present invention increases the interference diversity in systems with the frame structure described above by using frequency hopping sequences that are selected considering characteristics of the channel relating to how the channel varies. According to a first embodiment, the channel characteristics relateto channel coherence time and according to a second embodiment, the channel characteristics relate to channel coherence bandwidth. For channels with long coherence times, the transmission hops back and forth several times during a TTI on the different available frequencies. For channels with widecoherence bandwidths, hopping may be performed between the frequency used by the reference signals and its neighbor frequencies. For channels with both long coherence times and widecoherence bandwidths, a combination may be used.
