Embodiment
Below will be in detail with reference to the preferred embodiments of the present invention, the example shown in the drawings.In any possible place, in whole accompanying drawing, use identical reference number to represent same or analogous part.
In the detailed description of the present invention below, suppose that PLCM has the length of 42 bits.But, can this bit length be set according to current applicable standard.
Simultaneously, preceding ten bits (last ten bits) are allocated for the header of 42 bit PLCM, and when producing the PLCM of this F-BFCH of being used for and F-BSCH, use, should approve that the distribution of avoiding header value meets (overlapping) previous arbitrarily public long code mask and long code mask that uses.Fig. 2 and 3 each show according to the present invention the PLCM that produces, wherein the PLCM of Fig. 2 produces for the F-BFCH channel, and the header value with " 1100010000 ", and the PLCM of Fig. 3 is that the F-BSCH channel produces, and have the header value of " 1100010001 ".
With reference to figure 2 and 3, as above divide mix ten bits after, will broadcast/multi-point service flow identifier (BCMC_FLOW_ID) distributes to down 32 bits, and can have the length of one group of 16 bit, 24 bits and 32 bits.Under the situation of 16 bits and 24 bit identifier, fill the remainder that distributes, just, fill with 0 and 1.The content that produces flow identifier is used for specific broadcasting/multi-point service, and itself and transmission signals is multiplexed.Afterwards,, produce the forward channel that public long code mask is used to provide broadcasting/multi-point service based on broadcasting/multi-point service flow identifier as above, and multiplexed with the signal that receives, to decode at receiver side.Be broadcasting/multi-point service that the forward channel of carrying out through mobile communication system provides, receive the flow identifier of indication broadcasting/multi-point service, and based on the flow identifier that receives, produce public long code mask the channel that provides broadcasting/multi-point to serve is provided.The flow identifier that receives can be stored in the memory of mobile radio station and base station.
In the incident that sends a plurality of broadcasting/multi-point service flow identifier (each is assigned to a F-BSCH channel), can use any one generation PLCM of flow identifier.According to a preferred embodiment of the invention, the selection first broadcasting/multi-point service flow identifier (FIRST_FLOW_ID) as shown in Figure 4.In other words, if with the data multiplex of two or more broadcasting/multi-point service in a F-BSCH channel to be sent, select a broadcasting/multi-point service flow identifier to be used to produce the PLCM of multiplexed channel, and selected flow identifier preferably is assigned to the first broadcasting/multi-point flow identifier of corresponding F-BSCH channel.
On the other hand, according to the first embodiment of the present invention, if dividing the data of a broadcasting/multi-point service is used for through more than a F-BSCH Channel Transmission, PLCM produces needs other identifier, just, Channel Identifier (FSCH_ID), as shown in Figure 5, wherein the PLCM of Chan Shenging also uses Channel Identifier except the BCMC_FLOW_ID identifier of Fig. 2 and 3 or the FIRST_FLOW_ID identifier of Fig. 4.In other words, Channel Identifier is indicated specific F-BSCH channel, and is included among the PLCM that produces when a broadcasting/multi-point service is provided through a plurality of F-BSCH channels.
The configuration of PLCM as shown in Figure 5 can change according to the length of FSCH_ID identifier and header.In other words, though the FSCH_ID identifier normally is made up of seven bits, as shown in Figure 6, PLCM can be disposed multiplely.Especially, can not produce PLCM, the Bit Allocation in Discrete of lesser number can be given the FSCH_ID identifier if think that the FSCH_ID identifier of seven bits is oversize, with produce as shown in Figure 7 four bits or the FSCH_ID identifier length of three bits as shown in Figure 8.The FSCH_ID identifier can reduce to the length of five bits, so header value is " 11000 " or " 00xxx " or the length that reduces to six bits, so header value is " 1100 " or " 00xx ".
With reference to figure 6-8, show the PLCM that uses the FSCH_ID identifier to produce according to the example of first embodiment of the invention, be used to produce the Channel Identifier that length that broadcasting/multi-point service flow identifier (BCMC_FLOW_ID) of the PLCM of configuration as shown in Figure 5 makes it possible to use respectively full length channel identifier (FSCH_ID) or four bits or three bits reduces.In arbitrary situation, broadcasting/multi-point service flow identifier can have the length of 16,24 or 32 bits.If broadcasting/multi-point service flow identifier has the length of 16 bits or 24 bits, fill public long code mask by filling up remaining bits with 0 or 1.In the example of Fig. 6, use whole FSCH_ID identifier with the header of value with " 110 ", still the header value of " 000 " or " 001 " can be used to avoid the conflict with other channel.In the example of Fig. 7, only use four Least significant bits (FSCH_ID_LSB_4) of Channel Identifier with the header value of " 110001 ", the header value of " 00xxxx " can be used to avoid the conflict with other channel.In the example of Fig. 8, only use three Least significant bits (FSCH_ID_LSB_3) of Channel Identifier with the header value of " 1100011 ", the header value of " 1100001 " or " 1100010 " can be used to avoid the conflict with other channel.
In the example of Fig. 6-8, the FIRST_FLOW_ID identifier is a BCMC_FLOW_ID identifier that is assigned to corresponding F-BSCH channel.But in each situation, the BCMC_FLOW_ID identifier can have the length of 16,24 or 32 bits, as respectively as shown in Fig. 9,10 and 11 the example.When BCMC_FLOW_ID identifier length during,, just, fill the FIRST_FLOW_ID identifier and make and take whole 32 Bit Allocation in Discrete with 0 or 1 vacant (unallocated) bit of filling 32 Bit Allocation in Discrete less than 32 bits.Here, provide the upper bits of filling to 32 Bit Allocation in Discrete.
In the example of Fig. 9 and 10 and seven bit FSCH_ID identifiers and seven bit header use the BCMC_FLOW_ID identifier of 16 bits and 24 bits together, make 42 bit PLCM length need the filling length of 12 bits and four bits respectively.Here, as in the situation of the example of Fig. 8, header value is " 1100011 ", and still the header value of " 1100001 " or " 1100010 " also can be used to avoid and other channel confliction.But the example of Figure 11 does not need to fill, because the BCMC_FLOW_ID identifier has taken 42 bit lengths that whole 32 bit lengths and seven bit FSCH_ID identifiers and three bit header constitute PLCM.In this example, as in the situation of the example of Fig. 6, header value is " 110 ", and the header value of " 000 " or " 001 " also can be used to avoid and other channel confliction.
Figure 12 has illustrated according to another embodiment of the present invention, uses the example of the PLCM of BSR_ID identifier generation when sending a broadcasting/multi-point service through multiple F-BSCH channel.Here, PLCM comprises specific service flow identifier (BSR_ID), the particular B CMC data flow of its indication on one of F-BSCH channel, and preferably a BSR_ID identifier (FIRST_BSR_ID) and the first broadcasting/multi-point service flow identifier (BCMC_FLOW_ID).As in the situation of first embodiment, the BCMC_FLOW_ID identifier can be set to the FIRST_FLOW_ID identifier.
Therefore, the PLCM of Figure 12 configuration is the modification of first embodiment of the invention.In other words, according to a second embodiment of the present invention,, use BSR_ID to produce PLCM except the BCMC_FLOW_ID identifier of Fig. 2 and 3 or the FIRST_FLOW_ID identifier of Fig. 4.As in the situation of first embodiment, broadcasting/multi-point service flow identifier can have the length of 16,24 or 32 bits, and if broadcasting/multi-point service flow identifier have length less than 32 bits, then fill the PLCM that produces.Here, as in the situation of the example of Fig. 8-10, header value is " 1100011 ", and still the header value of " 1100001 " or " 1100010 " also can be used to avoid and other channel confliction.
Figure 13 has illustrated according to still another embodiment of the invention, when sending a broadcasting/multi-point service through multiple F-BSCH channel, uses the example of the PLCM of FSCH_ID and BSR_ID identifier generation.
With reference to Figure 13, the PLCM of generation comprises the Channel Identifier (FSCH_ID) of indicating specific F-BSCH channel and is used to discern the specific service flow identifier (BSR_ID) of the data flow of the particular B CMC service that sends through the F-BSCH channel.In this process, can be used as the BSR_ID identifier corresponding to the FIRST_BSR_ID of a BCMC_FLOW_ID identifier of distributing to corresponding F-BSCH channel.For finishing 42 bit lengths of PLCM, fill one or more specific parts according to the length (n) of header; Especially, with 0 or 1 upper bits of filling the FSCH_ID identifier portion.In other words, the length of filling depends on the length of header.For example,, fill length and become 32-n, make that with 0 or 1 filling upper bits, just, the header next door is the distribution of FSCH_ID identifier to finish if header length is n.
Should approve that each embodiment of the present invention can be realized by the module that constitutes a portable terminal or a base station.
Therefore, the present invention uses known broadcasting/multi-point service identifier to produce PLCM, promotes thus to distribute PLCM, has avoided the PLCM (or LCM) of current use overlapping and make it possible to reduce time of delay.
