Abstract:
In a wireless communication system, the uplink transmission of measurement reports may be scheduled based on an estimated time of when a measurement report will be ready for transmission. The estimated time may be calculated at a base station or user equipment.
Abstract:
A method for managing radio access comprises sending (210-211) of a radio access technology -RAT- resource aggregation request from a first radio access network -RAN- to a second RAN concerning communication with a user equipment connected to a source RAN, and returning (212-213) a response to the first RAN. The source RAN is the first or second RAN. The first and second RANs use different radio access technologies. Radio resources of a base station in a target RAN, the RAN to which the user equipment is not connected, are reserved (214). A report of the reserved radio resources is sent (216-217) to the source RAN. A RAT resource aggregation command is transmitted (218) to the user equipment. The RAT resource aggregation command comprises that a RAT resource aggregation shall be used and the reserved radio resources. The base stations have at least partly overlapping coverage areas.
Abstract:
UTRAN MAC-d multiplexing of data from multiple logical channels to a single MAC-d flow is supported while reducing overhead and achieving octet alignment in MAC-d PDU length. In one embodiment, the C/T field of a multiplexed MAC-d PDU is eliminated, and the logical channels multiplexed into the MAC-d flow are mapped to a MAC-hs PQ in at least the NodeB (and preferably in the UE as well). In other embodiments, the C/T field is retained, and an octet-aligned length indicator is transmitted from the RNC to the UE. In one embodiment, the length indicator is octet-aligned by padding the MAC-d PDUs. In another embodiment, transmitters and receivers in the path from RNC to UE are configured with an offset to add to the length indicator to achieve octet alignment. The padding or offset is (8-n) bits, where n=the number of bits in C/T field.
Abstract:
Disclosed is, among other things, a method of physical Random Access Channel (PRACH) selection in a User Equipment, (UE) where the UE selects PRACH non-randomly from a list of candidate PRACHs.
Abstract:
When a user equipment (UE) is in a CONNECTED state with a base station of a wireless network and is also in a discontinuous reception (DRX) mode, a DRX parameter such as DRX period for the UE is compared with a threshold. If the DRX parameter is at or below the threshold, the UE applies a network controlled mobility mode with UE assist where the network controls handover of the UE to another cell. If the DRX parameter is above the threshold, the UE applies a UE controlled mobility mode in which the UE is free to select a best cell. In this way, DRX benefit of reduced power consumption is maintained while the time period in which the UE is unreachable is minimized.
Abstract:
method and an arrangement (800) in a radio network node (140) for sharing of a first Cell Radio Network Temporary Identifier, referred to as “C-RNTI” between at least a first and a second communication device (110, 120) are provided. The radio network node (140) receives a first random access preamble from the first communication device (110). Furthermore, the radio network node (140) associates the first C-RNTI to the first communication device (110), in response to the first random access preamble. The radio network node (140) receives a second random access preamble from the second communication device (120). Moreover, the radio network node (140) associates the first C-RNTI to the second communication device (120), in response to the second random access preamble, while the association of the first C-RNTI to the first communication device (110) is maintained. A method and an arrangement (900) in a first communication device (110) for enabling sharing of a first Cell Radio Network Temporary Identifier between at least the first communication device (110) and a second communication device (120) are provided.
