摘要:
The present invention provides a method of determining capability of a UE, the method comprising: receiving an indication from a UE during a random access procedure, the indication enabling antennae capability of the UE to be determined; processing the indication in order to determine the number of antennae of the UE; and allocating resources to the UE according the antennae capability of the UE. The invention further relates to a user equipment and a network entity operable to implement such a method.

A procedure for RACH initial access in a mobile terminal is provided such that necessary information is conveyed the for the initial access procedure with less overhead. The method allow an accurate choice of the uplink transport format by allowing the mobile terminal to determine by itself whether a certain transport format may be used for the transmission of a message prior to the first preamble transmission and prior to the power ramping.

A method and apparatus for enhancement of the random access procedure of a Long-Term Evolution (LTE) system are provided. Enhancements include modeling one cycle in the random access procedure since only one counter is necessary and controlling the delay prior to the preamble transmission in order to reduce conflicts by multiple mobile terminals using the random access channel.

A method for accessing a wireless communication network includes transmitting a first message that has a first random identifier (RAND ID), and receiving a response to the first message such that the response includes the first RAND ID and signaling information. The method further includes transmitting a second message, having a second RAND ID, using at least one allocated resource. An alternative method includes communicating with a UE by receiving a first message from the UE. The first message includes a first RAND ID. The method further includes transmitting to the UE a response to the first message, and receiving a second message from the UE on at least one allocated resource. Typically, the response includes the first RAND ID and signaling information, and the second message comprises a second RAND ID.

The present invention provides a method of selecting a random access preamble in a radio communication system operable at least on a physical layer and a medium access control layer. Random access preambles are divided into at least two groups, the groups depending on at least one of the following: radio conditions and a size of a message to be transmitted by user equipment. The method comprising: (a) the medium access control layer selecting one of the preamble groups; (b) the medium access control layer randomly selecting one random access preamble within the selected group; (c) the medium access control layer signaling the selected random access preamble to the physical layer; and (d) the physical layer generating and transmitting the generated random access preamble.
摘要:
A method of determining random access resources performed by a mobile terminal, the method comprising: receiving information on available random access resources from a network; deciding how to derive the random access resources to be allowed based on default values or information received from the network; measuring received signal quality of at least one of a cell to be accessed and a neighboring cell; and deriving the allowed random access resources based on the deciding and the measuring.
摘要:
A method of changing a radio access configuration between a terminal and a network. The network performs the steps of: initiating a new configuration that is related to an old configuration for the same terminal; informing the terminal to apply the second configuration; and determining when the terminal uses the second configuration based on the reception of a radio signal from the terminal. The terminal performs the steps of: receiving information to apply a new configuration; transmitting, to the network, a radio signal indicating a change in configuration; and changing from an old configuration to the new configuration at a predetermined time after transmitting the radio signal.

The disclosure relates to a method for a method for a user equipment configured in carrier aggregation mode to assist an e Node B in estimating the total available output power for each component carrier. The method comprises reporting from the user equipment to the e Node B at least one of RF architecture information of the user equipment, and at least one power parameter value. The disclosure also relates to the corresponding e Node B, user equipment, computer program and storage medium.
摘要:
The present invention provides a method of configuring random access resources for random access transmission, the method comprising: determining a number n of preamble signatures that can be used for random access transmission; grouping the n preamble signatures into K groups j (j=1, 2K) wherein K corresponds to a number of downlink component carriers and K is greater than or equal to 2; assigning each group j to a respective downlink component carrier; assigning configuration data to each group j; and transmitting the group j configuration data on the corresponding downlink component carrier.
摘要:
A method of and apparatus for allocating radio resources to a UE according to the capability of the UE, wherein the radio resources to be allocated include a set of radio resources which are incompatible with a first type of UE and are compatible with at least a second type of UE, the method comprising: receiving a random access preamble from a UE; transmitting a first random access response assigning a first set of radio resources compatible with the first type of UE, and a second random access response assigning a second set of radio resources incompatible with the first type of UE; wherein the first random access response is scheduled differently in time and/or frequency to the second access response; receiving a connection request message from the UE; wherein, if the connection request message is received on the first set of radio resources it is determined that the UE is a UE of the first type; and wherein if the connection request message is received on the second set of radio resources, it is determined that the UE is not of the first type.
