摘要:
A method for transmitting an uplink signal by a user terminal includes: transmitting the uplink signal to a base station on a primary component carrier using allocated resource blocks (RBs), if a carrier aggregation (CA) is configured, if the configured CA corresponds to an intra-band CA, and if the configured CA corresponds to non-contiguous CA, wherein if a channel bandwidth by an aggregation of the primary component carrier and a secondary component carrier is at least one of 25 RBs, 50 RBs, 75 RBs and 100 RBs and if a gap between two sub-blocks corresponds to a predetermined range, the allocated resource blocks (RBs) in the primary component carrier is limited to 10 RBs to meet a requirement for a reference sensitivity on a downlink of the secondary component carrier.

A communications system for communications by a multicarrier transmission mode between a plurality of communications apparatuses (10, 20) wherein an overall frequency band assigned to the communications system is divided into a plurality of frequency bands each having a constant bandwidth (for example band 1 to band 4) and a specific band (for example band 1) among these divided bands is used to transmit used frequency band information and thereby determine the assignment of the remaining bands (band 2 to band 4) to be used between said communications apparatuses. Here, the specific band is defined as a main band for transmitting control channel information including said used frequency band information and also data channel information. The main band may also be added with an extension band for transmitting further data channel information. Further, the main band and extension band can be changed in the frequency band used along with time or can be changed in the number thereof. Both of the main band and the extension bands are preferably used by multiplexing by some of communications apparatuses.

Base station (BS) and mobile station (MS) methods and apparatus are provided. The BS configures an uplink sounding channel made up of at least one OFDM symbol in an uplink slot. The BS signals to the MS use and location of different configurations of the uplink sounding channel via a system configuration broadcast message. The uplink sounding channel comprises OFDM symbols where one or more of a subcarrier spacing and a sampling frequency is different from that of OFDM symbol used for data transmission. Each OFDM symbol comprises a sounding reference symbol corresponding to at least one transmit beam and is received by at least one receive beam to form at least one transmit-receive beam pair. The at least one transmit-receive beam pair for UL-SRS in different OFDM symbols are different. The sounding channel configuration is based on information received from neighboring BSs via inter-BS coordination over a pre-defined interface.

There is provided a method of transmitting an uplink for reference sensitivity test for intra-band non-contiguous CA in LTE-A system. The method may comprise: if a carrier aggregation (CA) is configured, if the configured CA corresponds to an intra-band CA, and if the configured CA corresponds to non-contiguous CA, transmitting an uplink on a primary component carrier using allocated resource blocks (RBs). if a channel bandwidth by an aggregation of the primary component carrier and a secondary component carrier is at least one of 25RBs, 50 RBs, 75 RBs and 100RBs and if a gap between two sub-blocks corresponds to a predetermined range, the number of the allocated resource block (RB) in the primary component carrier may be limited to 10 to meet a requirement for a reference sensitivity on a downlink of the secondary component carrier.

A display device comprising a display panel and a display cover plate positioned between the display panel and an observer. The display cover plate is housed within a protective frame (edge bracket) that protects edges of the display cover plate from damage. The edge bracket supports the edge portions of the display cover plate that are most likely to have flaws resulting from such operations as cutting and grinding, and minimizes flexing of the display cover plate, particularly at an edge, which could result in the formation of cracks at the flaw site and propagation of those cracks.

There is provided a base station accommodated in a communications system for exchange of information between a base station and mobile stations (10) by time division multiplexing using a plurality of frequency bands. The base station comprises a setting unit (15) configured to set a specific frequency band and one or more dedicated frequency bands for each mobile station from among a plurality of frequency bands assigned to the communications system when a wireless channel between the base station and the mobile station is established, wherein the dedicated frequency band is to be used for transmission of dedicated data information to each mobile station. The base station further comprises a transmission data generation unit (11) for each mobile station configured to generate dedicated data and dedicated frequency band information; and a transmission unit (13) configured to transmit the dedicated data and the dedicated frequency band information to the mobile station, by using the specific frequency band.
