Channel Configuration Method, Device and System

TECHNICAL FIELD

The present invention relates to the field of communications, and in particular, to a channel configuration method, a device and a system.

BACKGROUND

Currently, to ensure security of data transmission on a wireless network, a dedicated channel (DCH) is generally used to perform transmission and reception of data. During a process of transmitting data by using the DCH, a dedicated physical control channel (DPCCH) is in a continuous transmission and reception state all the time. However, when no data is transmitted, the DPCCH is also in the continuous transmission and reception state, which causes a waste of power, and even causes interference to transmission and reception of other signals.

To reduce power and reduce interference, a discontinuous transmission (DTX) and discontinuous reception (DRX) technology is introduced to a DCH, that is, the DCH is used to perform discontinuous transmission and discontinuous reception of data, so that when no data is transmitted, a DPCCH may not be in a reception state or a continuous transmission state, thereby reducing power, and reducing interference to transmission and reception of other signals. After the DTX and DRX technology is introduced to the DCH, researchers find that, a DTX and DRX gain may be maximized by shortening a transmission time interval (TTI) of data. However, transmission within a shorter TTI cannot be implemented unless an existing spreading factor (SF) is reduced, but reduction of the SF causes problems of reducing a downlink code resource and even limiting a code resource. Multi-user time division multiplexing is a necessity of reducing a downlink code resource. However, that multiple users multiplex a downlink dedicated physical channel (DPCH) in a time division manner may affect scheduling flexibility of High Speed Downlink Packet Access (HSDPA).

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

Embodiments of the present invention provide a channel configuration method, and the embodiments of the present invention further provide a corresponding network side device, a base station, user equipment and a network system, which are separately described in detail in the following.

Embodiment 1

As shown in FIG. 1, this embodiment provides a channel configuration method, including the following steps.

101: A network side device generates a channel configuration information, where the channel configuration information is used to configure a downlink fractional-dedicated physical channel (F-DPCH) and a downlink dedicated physical channel (DPCH) in a code division manner, where the downlink F-DPCH is used for transmission of transmit power control (TPC) information, and the downlink dedicated physical channel (DPCH) is used for transmission of data information.

102: The network side device sends the channel configuration information to user equipment (UE), so that the UE receives the downlink F-DPCH and the downlink DPCH according to the channel configuration information.

The channel configuration information generated by the network side device includes information used to configure the downlink F-DPCH and the downlink DPCH in a code division manner. The network side device sends the channel configuration information to the UE, and may configure both the downlink F-DPCH and the downlink DPCH in a code division manner for the UE. Likewise, the network side device sends the channel configuration information to a base station, and may configure both the downlink F-DPCH and the downlink DPCH in a code division manner for the base station.

After the downlink F-DPCH and the downlink DPCH are configured for the UE, because the downlink DPCH occupies only one code resource but can support data information transmission of multiple users, many downlink code resources can be saved, and a downlink capacity can be increased. The downlink F-DPCH is used for transmission of transmit power control TPC information, and because an F-DPCH is multiplexed by multiple users in a time division manner and TPC information of at most 10 users can be carried in one slot, TPC of another HSDPA user can also be transmitted at the same time when DPCH data is transmitted, thereby achieving an effect that DCH transmission and HSDPA transmission are not mutually affected, and ensuring scheduling of HSDPA while ensuring normal transmission of a DPCH. In addition, in the prior art, a downlink DPCCH is generally used for transmission of TPC information. However, in this embodiment, the downlink F-DPCH is used for transmission of TPC information, and the downlink DPCH may not be used for transmission of the control information but is only used for transmission of data information, thereby avoiding a relatively high peak-to-average ratio generated during a process of transmitting a downlink signal.

Embodiment 2

As shown in FIG. 2, this embodiment provides a channel configuration method, including the following steps.

201: A network side device generates channel configuration information, where the channel configuration information is used to configure a downlink fractional-dedicated physical channel F-DPCH and a downlink dedicated physical channel DPCH in a code division manner, where the downlink F-DPCH is used for transmission of transmit power control TPC information, the downlink DPCH is used for transmission of data information, and a timing relationship between the downlink F-DPCH and the downlink DPCH is one of the following relationships: timing of the downlink F-DPCH is equal to that of the downlink DPCH, or a difference between timing of the downlink F-DPCH and timing of the downlink DPCH is an integral multiple of 256 chips.

202: The network side device sends the channel configuration information to user equipment UE, so that the UE receives the downlink F-DPCH and the downlink DPCH according to the channel configuration information.

Specifically, when a value of a Default DPCH Offset Value of the downlink F-DPCH is an even multiple of 256 chips, that is, a product of 256 multiplied by 2n (n is an integer), timing of the DPCH channel is equal to that of the F-DPCH channel. That is, when a configuration parameter DOFF value of a channel is a multiple of 512 chips, timing of the DPCH channel is equal to that of the F-DPCH channel. For example, the Default DPCH Offset Value of the F-DPCH may be set to 0, 512 or 1024, so that timing of the DPCH channel is equal to that of the F-DPCH channel. When the value of the Default DPCH Offset Value of the downlink F-DPCH is an odd multiple of 256 chips, that is, a product of 256 multiplied by 2n+1 (n is an integer) (for example, when a DOFF value corresponding to the F-DPCH is a value such as 256 or 768), a difference between timing of the DPCH channel and timing of the F-DPCH channel may be 256 chips. Therefore, a timing relationship between the downlink F-DPCH and the downlink DPCH is one of the following relationships: timing of the downlink F-DPCH is equal to that of the downlink DPCH; or a difference between timing of the downlink F-DPCH and timing of the downlink DPCH is an integral multiple of 256 chips.

In this embodiment, during a process of configuring the downlink F-DPCH and the downlink DPCH, the channel configuration information sent by the network side device to the user equipment UE includes a default DPCH offset value and a timing offset DPCH frame offset of an F-DPCH frame relative to a primary common control physical channel P-CCPCH frame, and when both the downlink F-DPCH and the downlink DPCH are configured for the UE, the Default DPCH offset value and the DPCH frame offset meet one of the following conditions:

(Default DPCH Offset Value)mod 38400=DPCH frame offset, or

(Default DPCH Offset Value+256)mod 38400=DPCH frame offset,

where mod denotes a remainder operator.

To ensure that a configured channel can be normally used when a terminal is in a soft handover area, the following measures may be further used in this embodiment of the present invention. Specifically, the channel configuration information includes a default DPCH offset value and a timing offset DPCH frame offset_jof an F-DPCH frame relative to a primary common control physical channel P-CCPCH frame, and when both the downlink F-DPCH and the downlink DPCH are configured for the UE, the Default DPCH offset value and the DPCH frame offset_jmeet one of the following conditions:

(Default DPCH Offset Value)mod 38400=DPCH frame offset_j, or

(Default DPCH Offset Value+256)mod 38400=DPCH frame offset_j,

where j denotes the first radio link in the configuration information. It should be noted herein that, the channel configuration information sent by the network side device to the UE may include at least two radio links.

In this embodiment, the network side device may be a radio network controller (RNC). The RNC may further send the channel configuration information to a base station, so that the base station configures the downlink F-DPCH and the downlink DPCH.

It should be noted that, in this embodiment, the downlink DPCH may be a multi-user time division multiplexing channel, and may be shared by multiple users. Specifically, as shown in FIG. 3, users UE1, UE2, UE3 and UE4 multiplex a downlink DPDCH channel in a time division manner, and the users send respective data information within respective sending time periods, where the sending time periods of the users are equal. Therefore, the users may send respective data information at equal probabilities. For example, a transmission time interval is 40 ms, a sending time period of each user is 10 ms, and UE1, UE2, UE3 and UE4 may transmit respective data information in each transmission time interval, where UE1 transmits data information in the first 10 ms of each transmission time interval, UE2 transmits data information in the second 10 ms of each transmission time interval, UE3 transmits data information in the third 10 ms of each transmission time interval, and UE4 transmits data information in the fourth 10 ms of each transmission time interval, so that UE1, UE2, UE3 and UE4 multiplex a downlink DPCH in a time division manner.

When multiple users multiplex a downlink DPCH in a time division manner, in order to transmit necessary TPC information and ensure scheduling of HSDPA, the TPC information of the users is carried on an F-DPCH channel. In this way, multi-user time division multiplexing may be used to reduce a downlink code resource and ensure scheduling flexibility of the HSDPA. In addition, in the prior art, a downlink DPCCH is generally used for transmission of TPC information. However, in this embodiment, a downlink F-DPCH replaces the downlink DPCCH to transmit the TPC information; the downlink DPCH may not include the downlink DPCCH, and may not be used for transmission of the control information but is only used for transmission of data information, thereby avoiding a relatively high peak-to-average ratio generated during a process of transmitting a downlink signal.

302: The base station configures the downlink fractional-dedicated physical channel F-DPCH and the downlink dedicated physical channel DPCH according to the channel configuration information. That is, the base station may configure both the downlink F-DPCH and the downlink DPCH.

Optionally, in step 301 and step 302, a timing relationship between the downlink F-DPCH and the downlink DPCH is one of the following relationships: timing of the downlink F-DPCH is equal to that of the downlink DPCH; or a difference between timing of the downlink F-DPCH and timing of the downlink DPCH is an integral multiple of 256 chips.

where j denotes the first radio link in the configuration information.

Generally, the UE uses a downlink channel as a reference to perform timing on an uplink channel. Because the channel configuration information is configuration information of the downlink channel, the UE may perform timing on an uplink dedicated physical channel DPCH according to the channel configuration information after the downlink F-DPCH and the downlink DPCH are received. The step of performing timing, by the UE, on an uplink dedicated physical channel DPCH may include: performing timing, by the UE, on the uplink DPCH by using the downlink fractional-dedicated physical channel F-DPCH in the channel configuration information as a timing reference, so that the uplink DPCH is sent 1024 chips later than the downlink F-DPCH.

In this embodiment, the UE may set a configuration parameter DOFF value to the default DPCH offset value or a sum of the default DPCH offset value and 256.
